They are particularly diverse in tropical forests, where the caterpillars consume the leaves and flowers of various trees and shrubs, but neither moths nor caterpillars are much in evidence during the day; most Emerald moths are active at night, when they can be attracted to light traps. The caterpillars are cryptic, often resembling twigs or other parts of the plants on which they feed and, as in other Geometridae, they are known as loopers or inchworms because of their distinctive gait caused by a reduction in the number of their abdominal prolegs. 'The Geometrinae, which include about 2300 described species in 250 genera according to the global taxonomic database updated from Scoble, Gaston and Crook (1 995)) have an almost worldwide distribution. Approximately 470 species are known in the Neotropics, a region that has been the focus of a series of studies by the Geometrid Moth Research Team as part of The Natural History Museum's collaboration with the Instituto Nacional de Biodiversidad (INBio), Costa Rica. These studies have used the resources of the long-established collections of The Natural History Museum and other institutions, together with a large quantity of recently collected Costa Rican material. The latter has been made available by the extensive sampling carried out by INBio's parataxonomists, a team of locally trained field-workers. An important aim of this programme of research is to revise the taxonomy of selected geometrid taxa with the purpose of recognizing monophyletic groups and to provide a means of identifying tribes, genera and species through keys and descriptions. A further intention is to support the efforts of Costa Rica, in surveying and conserving its rich biological diversity, by contributing to the National Biodiversity Inventory. The present project sets out to build on recent revisionary studies of selected Neotropical genera of Geometrinae. Although dealing with only four genera, the

NEOTROPICAL EMERALD MOTHS 31 1 studies of Pitkin (1993) on Nmoria, Lissochlora and Chauarriella, and Cook and Scoble (1995) on Oospila covered approximately half of the Neotropical species of Geometrinae. The present paper reviews, at the generic level, all 38 Neotropical geometrine genera currently recognized, thus providing a context to our initial studies on Neotropical Geometrinae. Although regionally restricted, this study has been undertaken with awareness of the Geometrinae of the rest of the world so an important aim of the work has been to improve our understanding of the subfamily on a global basis by complementing recent studies of Geometrinae, notably in North America (Ferguson, 1985) and SE Asia (Holloway, 1996). MATERIAL AND METHODS This study is based on more than 3000 specimens of Geometrinae, examined from three main sources: the collections of The Natural History Museum, London, U.K. (BMNH) (primary types and large series of other Neotropical material), the National Museum of Natural History, Washington D.C., U.S.A. (USNM) (further primary types), and the Instituto Nacional de Biodiversidad, San Jost, Costa Rica (INBio) (extensive, recently collected, Costa Rican material). The bulk of the material from INBio was collected by Daniel Janzen, Winnie Hallwachs, and INBio s team of parataxonomists. Neotropical material forms the major part of the sample but the study is broadened by the examination of type species and a range of extralimital species in those genera that occur elsewhere. I examined more than 700 genitalia slides. Abdominal markings were noted or photographed prior to dissection. In the female, abdominal tergum A7 was separated from its corresponding sternum using the technique explained in Pitkin (1 993: 4 1). I have followed the convention of describing features of the male abdominal segment 8 under the heading Genitalia d, although, anatomically, they are pregenital structures. The colour photographs of whole moths are all to the same scale; other illustrations are not to the same scale. Lectotypes were designated where necessary, particularly since several species have mixed syntype-series. In selecting lectotypes, specimens were chosen that had already been labelled as the Type in the collections of the BMNH and the USNM unless there were good reasons for not doing so. References to citations of genus and species-group names, subsequent to the original descriptions, are given only where they are required to show the historical background to the reinstatement here of earlier usage. Revisions of Neotropical species of Chauarriella Pitkin, Lissochlora Warren and Nernoria Hubner (Pitkin, 1993), and of Oospila Warren (Cook and Scoble, 1995) have been published recently so are not given detailed treatment in the current work, Species of those genera are listed here with, in each case, any synonyms, the original genus, and type locality (country only). In the more detailed coverage of species of other genera, the country records given for each species are based on the examination of specimens specifically for this work. Some species are recognizable on external features but the identity of many others can be confirmed only by dissection of specimens; where this is yet to be carried out, the record is given with a question mark. Records of species from northern Mexico, although biogeographically Nearctic, are included in the present work because they are not covered by works on

TAXONOMIC CHARACTERS Certain characters once used to define and group the Neotropical genera of Geometrinae are now seen to be too variable to be relied on. Prout (1932: 20) regarded the presence or absence of a frenulum in the male as an important character at the level of genus and above. However, both states can occur within a genus. For instance, a frenulum is present in most males of Synchlora but absent from S. faseolaria. Both states also occur within Oospila (with the inclusion by synonymy of Urucumia by Cook and Scoble (1 995: 4)), Chloractis, including an undescribed species, and Phrudocentra, including two species here transferred from Chloractis. A few genera were defined primarily on the degree of fusion of the veins Sc + R1 and Rs in the hind wing but this character, like many aspects of the venation, is also subject to variability, e.g. in Cathydata and Lophochonita. I consider the degree of fusion of these veins to be of little taxonomic value without other more reliable supporting characters. On this basis I synonymize Prohydata with Hydata, and Cheteoscelis with Synchlora. However, I defer synonymy of Methydata with PachycopsZC in the absence of knowledge of the male genitalic characters of the former genus. Methydata might instead prove synonymous with Hydata, since the main distinction is in another variable character: the presence or absence of the apical pair of hind tibia1 spurs. Some geometrine genera are sexually dimorphic in this respect but both states occur in the same sex of different species within Rhodochlora, Oospila and Xerochlora among others.

NEOTROPICAL EMERALD MOTHS 313 Other extenzal features Most Geometrinae are green but the shade, either pure green, or olive, yellowish or greyish green, differs between some groups of genera. A high degree of homoplasy makes colour pattern (of the wings mainly) often an unreliable character at the generic level but it can be used to distinguish some genera. For instance Lophochorista, a genus defined by features including tufts on the metathorax, differs from other Geometrinae in wing pattern. Similarly, wing shape is sometimes subject to homoplasy but in certain genera it is a useful diagnostic character. Typically the outer margin of the fore wing is straight or slightly curved convexly and the outer margin of the hind wing is curved convexly but in several genera (e.g. Eualloea, Neagathia and Neocrasis) is shaped otherwise. Dorsal crests or tufts on the abdomen are of diagnostic value; in the Neotropical fauna a row of these is present only in Oospila and Lophochorista. Genitalia The terminology of the genitalia largely follows that of Mots (1 956) and Ferguson (1985); various male structures are labelled in Fig. 87. Male genitalic structure is distinctive in most species of Geometrinae and, in many cases, characterizes genera. At the genus level, important features include the shape of the valva and the form and position of the various processes that may be present on the valva, such as those ofnmoria (Fig. 11 1). Some genera differ in the shape and degree of development of the uncus and socii, and in the presence or absence of processes of the aedeagus. The tegumen, vinculum and uncus form a characteristic shape in certain genera including Dichorda and Phmdocentru (Figs 94, 1 18, 1 19). Abdominal sternite 8 is sometimes partly sclerotized (e.g. in Lophochorista (Figs 72, 73) and usually in Oospila (Fig. 75)). In the female (Figs 185-241), characters of the ostial region are of greatest diagnostic value at the species level and to a lesser degree in defining genera. Most other structures of the female genitalia vary from species to species but the shape of the signum is characteristic in certain genera (see discussion of diagnostic features of Geometrinae). The apophyses anteriores vary in length within genera and within species. The estimates of length given are based on examination of few specimens and are intended for use as a rough guide rather than as a definitive measurement. GEOMETRINAE (Characters based mainb on Neotropical genera) Adults (Figs 1-60).

Wing shape various but unless stated otherwise: outer margin of fore wing straight or weakly curved convexly, apex of wing sometimes sharp but not extended to the degree of causing a concavity in the outer margin, outer margin of hind wing curved convexly. Venation (e.g. Figs 6 1, 62): R,-R, of fore wing stalked. Sc + R, and Rs of hind wing usually either touching but not fused, or fused at a point or for a short distance; occasionally fused to midway along cell. M2 of hind wing arising from end of cell slightly nearer M, than M,. Frenulum often reduced or even absent (consists, unless stated otherwise, of a single bristle in male, and one or more finer, hair-like bristles and a few hairs in female). Hind tibia commonly with 2 pairs of spurs but sometimes with only 1 (apical) pair. Male hind tibia often with terminal extension, which may be as long or longer than first tarsal segment; often also dilated and with a hair pencil in a groove. Abdomen sometimes with white spots or other dorsal markings. Ansa of tympana1 organ usually narrow just above base, broader medially, narrowing to apex. Sternite 3 of male abdomen often with pair of fields of deciduous needle-like modified scales (as in Holloway, 1996: figs 241-243). Genitalia 8. Uncus often slender and rod-like, sometimes long, or broad at base and tapered, occasionally forked or with other modification; sometimes reduced, without process or with extremely short process. Socii semi-membranous or sclerotized, often well developed and sometimes long. Gnathos commonly a slender loop with a narrow pointed distal tooth but sometimes modified or incomplete. Valva usually much longer than broad, with a few exceptions, notably that of Gnathosocia; basic shape usually parallel-sided or tapered, sometimes with variously shaped processes of costa or ventral surface. Transtilla commonly a narrow or moderately broad band, sometimes weakly sclerotized and indistinct or incomplete, usually bilobate; sometimes modified: large and plate-like as in Chlorochlamys, Eueana and certain others, or fused with juxta to form anellar complex in Oospila and a few other genera. Juxta, except in genera with an anellar complex, usually a shield- or shovel-shaped plate or pouch. Coremata sometimes present at base of valva, towards saccus. Aedeagus typically with a ventral slender basal part and pointed apex, more-or-less cylindrical or swollen medially, usually more strongly sclerotized in a strip along one side; sometimes with spines or larger processes but usually without cornuti. Abdominal sternite 8 often extended posteriorly as 2 slight lobes with a shallow notch or scoop in between, less commonly with larger sclerotized processes; with or without midrib. Genitalia $2. Apophyses anteriores varying in length, ranging from extremely short to only slightly shorter than apophyses posteriores. Ostial region sometimes with various sclerotized preostial or postostial structures, separate or united. Ductus bursae membranous or with varying degree of sclerotization. Corpus bursae with or without signum in anterior half (signum in posterior half in Anomphax). Signum, when present, usually either bicornute or in the form of a ridge. Ovipositor valves short, oblique and covered in setae on small papillate projections. Dzscussion of diagnostic features Several features have been suggested as possible apomorphies for the Geometrinae by various authors. Holloway (1 996) discusses several ground-plan characters, mainly in the light of his studies of moths of the Austro-Oriental Region. To

318 L. M. PITKIN complement his findings, ahd the recent studies of Cook & Scoble (1992) and Cook et al. (1994), I add comments based on investigation of Neotropical representatives of the group. Holloway (1996) treats the Old World genus Dysphania as a tribe within Geometrinae and places all other members of the subfamily in the tribe Geometrini. Pending stronger evidence that these two tribes are sister groups, my current work continues to apply the conservative concept of classification of the subfamily (see under Tribal Classification of the Geometrinae). (1) The green colour so pervasive in Geometrinae is due to the presence of large quantities of the pigment geoverdin (Cook et al., 1994). It seems likely that this is an apomorphy of the Geometrinae. The majority of Neotropical Geometrinae are green, vivid or muted in shade, but several lack any obvious green areas and are brown (e.g. Neocrasis) or yellow (Xanthoxena). Although these genera were not tested by Cook et al., other brown or yellow Geometrinae that were tested did contain large amounts of geoverdin. (2) Reduction of the frenulum. A tendency towards this within the Geometrinae has been remarked on by Prout (1912: 2), and by Holloway (1996) as characteristic of his concept of Geometrini (i.e. Geometrinae excluding Dysphania). The frenulum is reduced or absent in many Neotropical Geometrinae; it is absent, for example, from both sexes of Anomphax, Cathydata, Dichordophora and Eucrostes, but well developed in others (e.g. Rhodochlora and males of Oospila). As discussed under taxonomic characters this character is variable even within some genera. (3) Shape of the ansa of the tympana1 organ: usually narrow just above base, broader medially, narrowing to apex. Cook & Scoble (1992) regarded this as a probable synapomorphy of the Geometrinae, present in all of their sample except the anomalous genus Dysphania Hubner (thus equivalent to Geometrini sensu Holloway, 1996). This state occurs in most Neotropical Geometrinae. The few exceptions that have the apex of the ansa broadened as in certain Ennominae or some other subfamilies include Tachyphyle pretiosa, Phrudocentra janeira and Phrudocentra kinstonensis. (4) A pair of fields of needle-like scales on sternite 3 of the male abdomen is present in most of the Geometrini sensu Holloway (1996). Paired fields occur in about twothirds of Neotropical genera, but are absent in the remaining third including Dichorda and Oospila. Paired fields, as opposed to the more widely shared general presence of setae on sternite 3, may be an apomorphy of the Geometrinae, in which case its occurrence outside the group, in the Desmobathrini sensu Holloway (1996) and occasionally in the Ennominae, would be homoplasious. The desmobathrine patches are more elongated than those of Geometrinae. (5) Socii well developed often with parallel reduction of uncus (Holloway s concept of Geometrini, i.e. Geometrinae excluding Dysphania). Tendencies within the Geometrinae towards dominance of socii over uncus are exemplified by several independently derived occurrences in Neotropical representatives: the Synchlorini, some Lophochoristini (Oospila and Telot~eta) and Rhodochlora mfaria. However, at the other end of the range of this variable character several geometrine genera have very weakly developed socii, without reduction of the uncus, notably Chloractis, Neagathia, Taclychlora and Tachyphyle. (6) Cruciform vinculum (Holloway, 1996: Geometrinae). Development of this structure (e.g. Fig. 92) in the region of the saccus is pronounced in some genera (e.g. Chlorochlamys, Chloropteryx, Phrudocentra and some species of Synchlora), weak in various others, and absent in the rest (including Eualloea, Eucrostes, Eueana and Telotheta). (7) Aedeagus usually with sclerotization reduced to a ventral longitudinal strip and

NEOTROPICAL EMERALD MOTHS 319 usually without true cornuti (Holloway, 1996: Geometrinae). The sclerotized strip of the aedeagus is often strongly developed; cornuti are rarely present except in Oospila, which sometimes has one cornutus or more. (8) Oblique papillate ovipositor valves (Holloway s concept of Geometrini). This character state is present in all the Neotropical representatives examined and in most other Geometrinae. (9) Bicornute signum (Holloway s concept of Geometrini). This character is less widespread in Neotropical Geometrinae than in the taxa reviewed by Holloway (1996). A version of this general structure (e.g. Fig. 228) occurs in various genera, namely Anomphax, Dyscheilia, Eualloea, Lissochlora, Oospzla, Paromphacodes and Telotheta. Others (Eueana, Lophochorista, Nemoria, Synchlora, Xanthoxena and possibly also Rhodochlora) differ in having a ridge or shallow pouch, and a signum is absent from several genera. A bicornute signum is present also in some boarmiine Ennominae (Holloway, 1993 [1994]: 167). In conclusion, the widespread occurrence of certain features in Neotropical representatives of the group adds support to their treatment as apomorphies of Geometrinae (Geometrini sensu Holloway, 1996). These are characters 1, 3, 7, 8 and possibly also 4. With regard to the other characters, Neotropical findings suggest that 2 is not an apomorphy of the Geometrinae and is instead likely to have arisen, probably more than once, within the Geometrinae; the status of characters 5, 6, and 9 needs further clarification. ~mmature stages Very little is known of the immature stages of Neotropical Geometrinae but those in some other regions of the world have been documented and illustrated by various authors, notably Ferguson (1985: 8-1 0, North American species) and Sugi (1987: pls 14-16, Japanese species). Patocka (1994) gives characteristics of the pupae of Central European Geometrinae and other Geometridae. Ferguson (1985: 9) discusses features of the larva diagnostic for the Geometrinae and follows McGuffin, (1967: 7-8) in giving the following combination of key characters: seta SV4 absent on A1 but present on A3, A4 and A5; seta MD1 conspicuous on anterior abdominal segments if dorsolateral projections are undeveloped; seta CD2 on anal proleg distinctly above level of seta L2. TRIBAL, CLASSIFICATION OF THE GEOMETRINAE The classification above the generic level within the Geometrinae needs much more investigation and integration on a global basis. Attempts at phylogenetic analysis, notably by Viidalepp (1981), have been too limited in taxonomic and geographic coverage to clarify the situation. A particular problem exists in resolving the relationships of the Old World genus Dysphania which is currently placed within the Geometrinae but is anomalous in several respects. Holloway (1 996) recognizes two tribes in the Geometrinae: the Dysphaniini, based solely on the Old World genus Dysphania and the Geometrini, including all other Geometrinae. Consequently he relegates to subtribal level the tribal groupings used by other authors. Further studies may well vindicate this solution but in view of the many issues yet to be resolved in the classification of the

320 L. M. PITKIN Geometrinae I defer adoption of this proposal in the current work. The tribal names that follow are all equivalent to the subtribal names of Holloway. Various tribal classifications that have been proposed are of limited value because they are restricted to certain geographical areas; however, they provide a useful starting point. Ferguson (1969 and 1985) classified the North American fauna in five tribes and Inoue (1 96 1) classified the Japanese genera in thirteen tribes. Ferpson s framework accommodates many Neotropical genera but requires some revision when examined against this broader geographical background. For instance one of the chief characters that Ferguson used to define the Nemoriini, the length and shape of the socii in relation to the uncus, is now known to be much more variable than originally supposed, not only between genera but within the highly diverse genera Nemoria and Lissochlora. The characters given below, taken as a combination, define the Nemoriini better than before but are still not entirely satisfactory. As individual characters, few of them are unique to the Nemoriini nor are they present in all members of that group. The definitions of certain other tribes are open to question: the diversity of structure seen, not just within tribes but within certain Neotropical genera, weakens the case for recognizing tribes based on a single genus, such as the Dichordophorini, and the Old World tribes Timandromorphini and Neohipparchini of Inoue. Nine Neotropical genera are left whose relationships with any existing tribes are not yet resolved. There is little overlap between New World and Old World genera. That only two Neotropical genera occur also in the Old World is believed to reflect a true situation rather than an artificial consequence of a regional approach to geometrine taxonomy. Three of the five tribes discussed below are confined to the New World; of the other two, the Nemoriini have some Old World representatives (genera formerly in the Ochrognesiini) and the Hemitheini are primarily Old World. For discussion of groups that occur exclusively in the Old World see Holloway (1 996). In addition to the above studies, one by Stekol nikov and Kuznetsov (1981) recognized two supertribes, Comibaenidii and Geometridii, but although they considered these to encompass the holarctic Geometridae, their study sample was restricted to the fauna of the USSR. Tribe Nemoriini Gumppenberg, 1887 Holloway (1996) defines the group (as a subtribe) largely on the following characters of the male abdomen and genitalia. New World findings are included to complement and qualify his studies. (1) Abdominal sternite 8 with a sclerotized longitudinal midrib (e.g. as in Fig. 74): this is strongly developed in flmoria, less so in Rhodochlora, weak or incomplete in Lissochlora, Hyalochlora, Paromphacodes, Poecilochlora and irhrasychlora, rarely present in Chavarriella, and absent altogether in several other genera. A midrib occurs also in some members of the Synchlorini and in the Comibaenini. (2) Uncus rod-like, not pointed, often elongate and slender. A rod-like uncus is characteristic of all nemoriine genera except Lissochlora where it is presumed to be secondarily modified in the albociliaria group. The uncus is spatulate in Chavarriella, Poecilochlora, fjvochlora, the exclusively North American genus Chlorosea, and some

NEOTROPICAL EMERALD MOTHS 321 Nemoria, Phrudocentra and Dichorda species. The Hemitheini have a rod-like uncus but this is usually pointed and the socii lie parallel to it or are convergent, not divergent as they are when developed in the Nemoriini. A spatulate uncus is seen in Hydata, a genus which has no obvious relationship with the Nemoriini and is currently unplaced. (3) Valva with a differentiated sclerotized costal region, often with processes, particularly in Nmoria. The value of this as a tribal character is limited: sclerotization of the costal region is weak in Chauamella, Chloractis, Phrudocentra, &rochlora and Tachychlora but present in certain genera outside the Nemoriini e.g. Synchlora (Synchlorini) and Chlorina (Hemitheini). (4) The nemoriine saccus is sometimes bilobed. Ferguson ( 1985) describes the conspicuous dorsolateral protuberances of the larva, usually plate-like and most pronounced on abdominal segments 1-5. The larva is known in Jvmoria, Phrudocentra, Dichorda and Chlorosea; the dichordophorine larva is similar. The larva of Tachyphyle, a Neotropical genus whose relationships are currently unresolved, has very large dorsolateral plates. Dorsal protruberances are typical also of Geometra, in the Old World Geometrini, but these are conical, not plate-like. The nemoriine larva is typically a foliage feeder but a few flower feeders are known: Jvmoria arizonaria (Grote) (from North America) (see Greene, 1989) and Phrudocentra (oubrica?) from Costa Rica. All the nemoriine characters of the abdomen and genitalia are well developed in the Old World tribe Ochrognesiini Inoue (1 96 1) which is consequently considered to be a junior synonym of Nemoriini (see Holloway, 1996). Genera: Neotropical Neotropical and Nearctic Cathy data Chavarriella Chloractis Hy alochlora Paromphacodes Poecilochlora &ochlora Rhodochlora Tachy chlora lhrasy chlora Dichorda Jvmoria Phrudocentra Nearctic Chlorosea Old World Ochrognesia and Ochrognesiini) related genera (formerly in Tribe Dichordophorini Ferguson, 1969 The tribe includes just the genus Dichordophora. The most distinctive feature is the two-pronged uncus flanked by sclerotized socii in the male genitalia. Ferguson (1 985) describes the larva as similar to that of Nemoriini but with a continuous series of crochets instead of the two groups usual in Geometrinae.

322 L. M. PITKIN Genus: Neotropical and Nearctic Dichordophora Tribe Synchlorini Ferguson, 1969 The Synchlorini are characterized by the male genitalia in which the uncus is reduced and the socii are rigidly sclerotized, tapered and pointed. According to Ferguson (1985) the synchlorine larva, typically a flower feeder, has weakly developed dorsolateral protuberances which it covers with snippings of flowers and other plant fragments throughout the larval stage. Holloway (1 996) cites similarities with the Old World group Comibaenini (Comibaeniti in his treatment) in genitalic structure and in larval behaviour. Various other geometrine larvae attach plant debris to their bodies but only in the early instars. Genera: Neotropical Neotropical and Nearctic Xenopepla Synchlora Tribe Lophochoristini Ferguson, 1969 In thc Lophochoristini the valva has a ventral (usually medio-ventral) sclerite. This occurs also in the Old World Rhomboristini with which Holloway (1996) suggests a relationship, and in various Geometrinae that have no obvious relationship to the Lophochoristini e.g. Tarhyphyle, which is currently unplaced, and Chlorissa, which is in the Hemitheini. Various other features occur in some but not all lophochoristine genera. The transtilla and juxta are fused to form an anellar complex surrounding the aedeagus in Oospila, Anomphax and Telotheta but not in Eueana. Although there is no clear development of this in Lophochorista some species have a weak connection between the transtilla and juxta. Abdominal sternite 8 is usually modified with a sclerotized posterior margin or with processes in hphochorista, Oospila and Telotheta but it is not modified in Anomphax and Eueana. The abdomen has a row of prominent tufts of long scalcs in Lophochorista and Oospila but not in the other three genera. According to Ferguson (1985) th? larva, known for Eueana, is similar to the hemitheine larva. c' Tenera: Neotropical Neotropical and Nearctic Anomphax Telotheta Oospila Eueana Lophochorista Tribe Hemitheini Bruand, 1846 The Hemitheini Jensu strict0 are characterized by the male genitalia in which the uncus is slender, rod-like and pointed or tapered, and the socii are usually similar to the uncus in shape and size. The socii lie close to the uncus, parallel or convergent.

NEOTROPICAL EMERALD MOTHS 323 Abdominal sternite 8 is simple in the Neotropical representatives but some Nearctic and Old World taxa are modified with one or two pointed posterior processes. The dull colour of the moths is prone to fading and preserved specimens are brownish or yellowish-green, not pure green as typical of the Nemoriini. The wings do not have translucent patches as in Hydata and various other genera. The outer margin of the hind wing is often angled at vein M3 but this is seen also in genera outside the Hemitheini. Eualloea bears a general resemblance to the Hemitheini but it has highly complex genitalic structures and its relationships are unclear. Holloway (1 996) recognizes a broad concept of the Hemitheini (Hemitheiti in his treatment) with more varied morphology. The pan-tropical genus Eucrostes and various Old World taxa included in his concept are bright green and the uncus sometimes has a notched apex. The relationships of Eucrostes are unclear; it is possible that it may have affinities with the Lophochoristini (see the discussion under the diagnosis of Eucrostes). Holloway describes the male hemitheine antennae as often having untidy pectinations but Neotropical representatives have the usual comb-like, regular arrangement of pectinations. The hemitheine larva is usually simple and twig-like, rarely with abdominal protuberances.

Adults (Fig. 1). Antennae bipectinate in both sexes; interantennal fillet white or yellowish. Wing pattern: plain, without antemedial, postmedial, or terminal lines; fore wing green, often pale, with or without green discal spot; hind wing white, tinged with green, or very pale green, usually paler than fore wing. Venation: Sc + R, and Rs of hind wing touching but not fbsed. Frenulum absent from both sexes. Hind tibia with one (apical) pair of spurs; without distinct terminal extension. Abdomen predominantly whitish, without spots; a few tiny hairs projecting dorsally may represent rudimentary crests. Sternite 3 of male abdomen without pair of fields of modified scales (inferred from absence of enlarged scale bases). Genitalia 8 (Figs 63, 86, 136). Uncus short and tapered. Socii semi-membranous, small. Gnathos a short loop with a narrow distal tooth. Valva with squarish, slightly serrated-edged, ventral sclerite. Transtilla and juxta fused to form anellar complex surrounding acdcagus. Coremata absent or not noticeably developed. Aedcagus with finger-like process; spinose area on aedeagus and on process. Abdominal sternite 8 wcakly extended posteriorly as two slight lobes separated by distinct U-shaped excision; without midrib. Genitalia 9 (Figs 185, 227). Apophyses anteriores about one-third length of apophyses posteriores. Ostial opening irregular, slightly wrinkled. Ductus bursae lightly sclerotized, slightly bulbous, very short (much shorter than elongate pear-shaped corpus bursae). Signum with two small spines or papillae, in posterior half of corpus bursae. Diagnosis. Anomphax resembles Paromphacodes and the bistriaria group of Synchlora in having whitish hind wings and greenish fore wings but unlike those genera it has plain wings without postmedial line, terminal line or brown fringe. Wing markings are sometimes very weak in Paromphacodes but both pairs of tibia1 spurs are present in that genus. The male genitalic structure of Anomphax (Fig. 86), unlike that of Paromphacodes or Synchlora, indicates a close relationship with Oospila (Figs 1 12, 1 13) but An,omphax lacks the abdominal crests of that genus.

Venation: Sc + R, and Rs of hind wing touching, occasionally fused at a point or for a short distance. Frenulum absent from both sexes (pulchem'ma) or present (unnamed species, known only from males). Hind tibia with two pairs of spurs and male hind tibia with terminal extension (pulcherrima) or with one (apical) pair of spurs and without terminal extension. Metathorax sometimes with slight tuft of raised scales. Abdomen with a few small, usually indistinct, white spots. Sternite 3 of male abdomen with (pulcherrima) or without pair of fields of deciduous needle-like modified scales. Genitalia 8 (Figs 65, 89, 139). Uncus long or moderate, very slender and rod-like. Socii semi-membranous, tiny and not normally erect. Gnathos a slender loop with a narrow pointed distal tooth. Valva broad at base, tapered, without processes.

:i 3 2 I,. M. PITKIN Vinculum somewhat elongated and with sides distended (as in Phrudocentra but less pronounced). Coremata well developed as dense hair-like tufts on large extensible membranous sac. Aedeagus with pointed or rounded sclerotized apex. Abdominal sternite 8 very weakly extended posteriorly as a slight lobe or as two slight lobes with a shallow notch in between; without midrib. Genitalia 9 (Fig. 188). Apophyses anteriores more than two-thirds length of apophyses posteriores. Ostial opening with short sclerotized collar discontinued dorsally. Ductus bursae merged with elongate corpus bursae. Corpus bursae without signum. Dzagno.ris. The wing pattern together with the shape of pulcherrima (Fig. 5), the only described species now placed in Chloractis, is highly distinctive. An undescribed species of plainer appearance differs from other geometrines whose wings have thinly scaled pure green areas and a brownish basal patch in having only one pair of hind tibia1 spurs. lhe relationship of Chloractis with Phrudocentra needs investigation; these genera have very similar male genitalia and may even prove to be synonymous. The female genitalia differ mainly in the more elongate corpus bursae of Chloractis, and its ductus bursae sclerotized only as a short collar at the ostial opening. Di.rtribution. Central and South America from Belize to French Guiana and Brazil. Species. One species plus one (or possibly two) undescribed species.

NEOTROPICAL EMERALD MOTHS 333 from female. Hind tibia with one (apical) pair of spurs in male, two pairs of spurs in female; male hind tibia with terminal extension. Abdomen without distinct spots or crests but sometimes with diffuse brown markings near base. Sternite 3 of male abdomen with pair of fields of deciduous needle-like modified scales. Genitalia 6 (Figs 90, 149). Uncus slender, rod-like and pointed. Socii lightly sclerotized, tapered, almost as long as uncus; usually very slender but occasionally broadened subapically in extralimital species. Gnathos absent (Neotropical species), or a loop without distinct distal tooth but occasionally with slight distal process (extralimital species). Valva with spine-like costal and medio-ventral process (Neotropical species), with spine-like or variously shaped costal and medio-ventral or basal, but not basal costal, processes (extralimital species). Transtilla typically a narrow band but large and plate-like in some extralimital species. Juxta typically small (shallow in the Neotropical species). Coremata consist of hair-like tufts on extensible membranous sac. Aedeagus without any spines (Neotropical species); usually with many spines or spinules and often with one or more sclerotized processes (extralimital species). Abdominal sternite 8 more-or-less unmodified (Neotropical species), or with finger-like posterior process (type species and many other extralimital species); without midrib. Genitalia $? (Fig. 189). Apophyses anteriores slightly less than half to slightly less than two-thirds length of apophyses posteriores. Ostial surrounds with various sclerotized structures; postostial plate usually well sclerotized and broad. Ductus bursae often with sclerotized antrum merged with ostial surrounds; usually much shorter than corpus bursae. Corpus bursae elongate, sometimes oval or pear-shaped, without signum. Diagnosis. The Neotropical species of Chlorissa resembles other Hemitheini (Chlorochlamys, Chloroptelyx and Xerochlora), which have brownish, olive, or yellowish-green wings without translucent patches. Chlorissa is distinguished by features of the postmedial and terminal lines together with the lack of striations on the costa of the fore wing, and the simple male antennae. The spine-like process of the valva is distinctive in the sole Neotropical species. Remarks. The above description of wing pattern and shape is based on the Neotropical species alone and does not apply to many other species. However, the females of the Neotropical species are unknown and all female characters are based on Old-world species. According to Prout (1935: 15) the oriental genus Aoshakuna Matsumura (sole species: Aoshakuna sachalinensis Matsumura) is a possible synonym of Chlorissa. Biological notes. Host-plants of the Neotropical species are unknown. C, viridata, the type species of Chlorissa, has been recorded on various plants in Europe; young stages of this area described and figured by authors including Burrows (1 908: 130-1 35). Distribution. In the Neotropical Region known from Peru and recorded by Warren (1 909: 7 7) also from Surinam and Trinidad; [many Old World species exist]. Species. Approximately 40 species (1 Neotropical). Genitalia examined: decipiens (a), plus 16 extralimital species (d), 5 extralimital species ($?), including viridata (8 and 9).

Gnathos a rather weakly sclerotized, occasionally incomplete loop, basal part usually fused with tepmen; without distal tooth or occasionally with tiny tooth. Valva narrow and slightly tapered, with row of bristles or hairs on median ridge; without other processes. 'I'ranstilla large and plate-like with transverse sclerotized midrib. Juxta often small. Coremata consist of hair-like tufts on extensible membranous sac. Aedeagus usually with fine longitudinal ridges ending in a few small serrations at apex. Abdominal sternite 8 unmodified; without midrib. Genitalia 9 (Fig. 190). Apophyses anteriores slightly more than one-third length of apophyses posteriores. Ostial region usually with membranous or sclerotized preostial pouch; postostial plate usually large, usually strongly or lightly sclerotized but membranous in a North American species. Ductus bursae membranous, much shorter than corpus bursae. Corpus bursae pear-shaped or round, without signum. Diagnosis. Chlorochlamys resembles Chlorissa, Chloropte?yx and Xerochlora (see also the diagnoses of those genera) but the nearly smooth postmedial lines and lack of other obvious wing marlungs distinguish it from those. Differences in genitalic structure between Chlorochlamys and Chloropteyx are slight but in the male of the former the transverse midrib of the large plate-like transtilla is characteristic.

Dichorda is extremely similar to Dichordophora superficially hut it is distinguished by the markings on the inner side of the fore femur. The two genera differ strongly in genitalic structure, particularly in the male uncus which is usually rod-likc in Dichorda (Fig. 94) and two-pronged in Dichordophora (Fig. 96). Remarks. The distinctively patterned species porphyr0pi.s (Fig. 1 1) is incorrectly placed in Dichorda. Although the thick oblique postmedial lines give it the appearance of a Dichorda species, various other external features and the male genitalia differ markedly from the characters described above for that genus. Dichorda poqhyropis appears to be related to Jaccida, a species currently misplaced in Phrudocentra (see remarks for that genus). Although Dichorda generally lacks a frenulum in the female, an apparent trace of this uccurs in a North American species, illusharia. The North Amcrican species Dichorda iridaria (Guenite) has been recorded also from Mexico, by Delfh-Gonzalez & Beutelspacher (1986: 427), but this record requires confirmation; it may have been based on a misidentification of consequaria.

The structure of the signum and postostial pouches in the genitalia of the single female representing the genus is similar to that seen in Lissochlora. Dyscheilia is distinguished from Lissochlora, and from other plain green geometrines with regular wing margins and without abdominal crests, by the presence of one instead of the usual two pairs of hind tibia1 spurs.

Female antennae pectinate with short broad branches lying close together and forming single loops, not pairs of separate branches. Usually with white interantennal fillet. Wing pattern: thinly scaled, yellowish green or brownish with translucent patches, without terminal line. Outer margin of hind wing typically angled at vein M,, sometimes slightly scalloped. Venation: Sc + R, and Rs of hind wing fused to approximately midway along cell or fused only at a point, or occasionally touching but not fused. Frenulum weak or absent from female. Hind tibia with two pairs of spurs; male hind tibia usually with well developed terminal extension but in a few species extension tiny or absent. Abdomen olive or ochreous green dorsally, without spots or crests. Sternite 3 of male abdomen with pair of fields of deciduous needle-like modified scales. Genitalia 8 (Figs 70, 102-104, 151-153).

Socii semi-membranous, narrow or tapered, variable in size, not normally erect. Gnathos sometimes a slender loop with a narrow pointed distal tooth (distal tooth an extremely large hook in propinqua) but in other species gnathos modified as a broad loop, spinulose or with pair of spinulose processes, with distal tooth; in apz'cata two pairs of large distal spinelike processes replace tooth. Valva usually narrow, parallel-sided; sometimes with a few tiny spines near base; some others with a ventral sclerite bearing spines or spinelike processes, medial or towards apex or base of valva. Valva with basal costal process in a few species and costal spine-like process in pouera; occasionally without any processes. Transtilla usually weakly sclerotized or not at all, apart from distinctly demarcated funnel-shaped lobe at each end where it joins base of valva; lobes usually diverging.

Hydata, Methydata and Pachycopsis are small moths that have a similar wing pattern of yellowish green or brownish with translucent patches. Hydata, unlike the others, has two pairs of hind tibia1 spurs. Remarks. Prohydata and Hydata were treated as distinct because of the greater degree

352 1,. M. PITKIN of fusion of the veins Sc + R, and Rs in the hind wing of moths assigned to the latter; howcver, the variability of this character precludes any clear cut distinction. Moreover, differcnces in thc venation do not support apparent relationships of certain species of Prohydata and Hydata based on the structure of the male genitalia. Prohydata is here regarded as a synonym of Hydata. I11 the male genitalia of Hydata the demarcation of the funnel-shaped lobes from the median band of the traiistilla, more obvious in some species than in others, appears to be an autapomorphy for the genus. Gnathosocia also has transtilla lobes without a sclerotized median band but these are not obviously funnel-shaped and thcy converge, whercas those of Hydata usually diverge. Funnel-shaped lobes in certain other genera, including those sometimes seen in Synchlora, usually merge more smoothly with the median band of the transtilla; this is also the case in one apparently undescribed flydata species but that species has a strongly modified transtilla. The basal costal process of the valva sometimes seen in flydutn is considered to be derived independently from that of Nmoria. As in Pachycopsis the female antennae may appear to be merely thickened but close inspection reveals their pectinate structure. Some Hydata species are sexually dimorphic in wing pattern.

Type species: AplodeJJEav$irnbriu Warren, 1897: 423, by original designation. Adults (Figs 22, 23). Male antennae often strongly bipectinate, length of longest antenna1 branches ranging from nearly twice to more than 7 times width of flagellum at same point; female antennae simple; interantennal fillet white. Wing pattern: ground colour green; plain or with brown speckles, usually confined to postmedial and antemedial lines (in addition to discal spots) but other speckles present in a few species. White antemedial and postmedial lines represented by dots on the veins in the majority of species; wings usually with reddish brown terminal line, sometimes weak. Wings (in diurita group) less curved than usual for Geometrinae. Venation: Sc+R, and Rs of hind wing touching but not fused. Hind tibia with two pairs of spurs; male hind tibia with terminal extension. Abdomen green dorsally, usually with 3 or more white spots which are plain or ringed with reddish brown and sometimes with black or dark brown spot at anterior end. Sternite 3 of male abdomen with pair of fields of deciduous needle-like modified scales. Genitalia 8 (Figs 7 1, 105, 106, 154, 155) Uncus short or moderately so, broad to very slender, variously shaped. Socii extending nearly as far as uncus to slightly beyond uncus; variously shaped. Gnathos either a slender loop with a narrow pointed distal tooth or a broader loop with distal tooth often broad and blunt. Valva variously shaped though often with strongly broadened costal side; costal side sclerotized, without basal costal process (or at most with weak development of this), usually with distal process. Juxta funnel-shaped with tiny to large closed papilla, a cone, or flat plate without papilla. Corcmata usually present, well-developed as a dense brush in most species, sac short or of moderate length. Aedeagus often sinuous; with slight thorn-like projection, bulge or kink, normally in apical half. Anellar plate small to large; usually extending to middle or cwo-thirds length of aedeagus but occasionally to beyond apex of aedeagus. Abdominal sternite 8 usually very weakly extended posteriorly as two lobes with broad shallow notch; much broader than long, often much shorter than tergite; midrib usually weak or absent, rarely strongly defined.

3 5 8 I,. M. PITKIN Genitalia 9 (Figs 200, 20 1, 232). Apophyses anteriores less than one-quarter to slightly more than half length of apophyses posteriores. Species with or without somewhat sclerotized pouch joining ostium and abdominal sternite 7. Ductus bursae much shorter than abdominal segment 7 or (albocilzaria group) as long as or longer than segment 7; membranous apart from short sclerotized antrum in form of a collar split dorsally. Corpus bursae very slender and elongate or (albociliaria group) with large bulbous anterior part; with or without signum; signum, if present, in form of pouch with two projecting corners. Diagnosis. Lissochlora resembles various species of Nemoria and &nchlora externally but differs from both genera in genitalic features, lacking the well developed basal costal process of the valva of Nemoria and the reduced uncus and modified socii of kyynchlora. The slight projection or kink of the aedeagus otlissochlora does riot occur in Nevioria or,synrhlora but it is seen in Poecilochlora and sometimes in Paromphacodes (see the diagnoses and remarks on those genera). Lissochlora differs from most species of Synchlora in the veins Sc + R, and Rs of the hind wing; these are touching but not fused in Li.r.sochlora whereas in &nchlora they are usually fused for a short distancc. Differences in wing pattern and shape distinguish many but not all species of Lissochlora from Nmoria (see the key to genera). Distribution.

Adulls (Fig. 24). Male antennae strongly hipectinate; female antennae bipeclinate with branches nearly as long as in male; white interantennal fillet often absent or indistinct, but distinct in calliope. Wing pattern: ground colour green; two irregular whitish transverse bands with waved edges, usually broad; antemedial band near base ofwing; postmedial band near or at outer margin, with brown markings at least at anal angle (North American species with pale brown antemedial band and brown postmedial blotches); green areas of wings usually liberally flecked with white in Neotropical species. Brown markings sometimes darker on under-side of wings. Venation: Sc + R, and Rs of hind wing either touching but not fused, or fused for a short distance. Frenulum apparently absent from female. Hind tibia with one (apical) pair of spurs; male hind tibia very strongly swollen at apex but without distinct terminal extension. 'Thorax and abdomen generally robust; thorax, or at least xnetathorax, covered with tufts of raised brown scales. Abdomen predominantly brown with line of 3 prorninerit tufts or crests of long narrow brown scales, on segments 2-4. Sternite 3 of male abdomen usually with pair of fields of deciduous needle-like modified scales, occasionally weak. Gnitalia 8 (Figs 72, 73, 107, 156). Uricus short, tapered, somewhat pointed. Socii semi-membranous, fairly narrow. Gnathos a fairly short loop with a narrow distal tooth. Valva broad with sclerotized costa and small lobe-shaped costal processes, one medial or slightly distal and another near base; valva with large medio-ventral sclerite which is spinose or with a single large spine-like process. Transtilla a very large plate. Coremata consist of hair-like tufts on extensible membranous sac, or often absent. Aedeagus with one or occasionally more large apical spine-like processes; sometimes with median spinulose patch. Abdominal sternite 8 with projecting sclerotizcd posterior margin, usually serrated, truncate or forming two pointed lobes; without midrib. Genitalia 9 (Figs 202, 233). Apophyses anteriores about one-fifth to more than half length of apophyses posteriores. Usually with distinct sclerotized postostial structure, either plate or ridge (but not evident in the type species). Ductus bursae usually sclerotized, extremely short (much shorter than pear-shaped, usually elongate, corpus bursae). Signum a straight or slightly curved ridge. DiaLgnosis. The wing pattern of Lophochorista is somewhat similar to that of Eueana and certain species of Oospila. Eueana lacks abdominal tufts (see also the discussion of that genus); Lophochorista and Oospila both have these but Lophochorista alone has tufts also on the thorax. The male genitalia of Lophochorista and Oospila have features in common, including the presence of a medio-ventral sclerite in the valva, hut whereas the traristilla and juxta form a fused complex in the latter they are separate or only weakly connected in the former.

Length of longest antenna1 branches in male up to about twice width of flagellum at same point, occasionally longer: 3 or 4 times width of flagellum; female antennae simple (except winniae in which they are bipectinate). White interantennal fillet present in most species. Wing pattern: ground colour green, sometimes with brown speckles, blotches or occasionally bands. Plain-winged species usually have waved or smooth white antemedial and postmedial lines and reddish brown terminal line, which are absent from most patterned species; postmedial line or hind wing usually bent at middle (distinctly so in most Neotropical species). Outer margin of hind wing often slightly angled at vein M,, in a few speckled species very slightly scalloped. Venation (Fig. 6 1): Sc + R, and Rs of hind wing touching but not fused. Frenulum sometimes weak or occasionally absent from female. Hind tibia with 2 pairs of spurs; male hind tibia with terminal extension. Abdomen commonly green dorsally with 3 or occasionally more white dorsal spots which are usually ringed with reddish brown; alternatively with dark brown spots or (rarely in Neotropical species) lackings spots. Sternite 3 of male abdomen with pair of fields of deciduous needle-like modified scales. Genitalia S (Figs 74, 11 1, 158).

Abdominal sternite 8 usually extended posteriorly as two slight rounded or occasionally pointed

NEOTROPICAL EMERALD MOTHS 365 lobes with V-shaped notch between; similar in dimensions to tergite or slightly shorter, often squarish; with midrib, usually distinct. Genitalia 0 (Figs 205, 206, 234). Apophyses anteriores commonly half length of apophyses posteriores or more, but reduced in some species. Majority of species with somewhat sclerotized and wrinkled pouch joining ostium and abdominal sternite 7. Ductus bursae usually much shorter than corpus bursae, usually membranous but occasionally with sclerotized antrum. Corpus bursae elongate, usually slender with bulbous anterior end. Corpus bursae with fairly small or occasionally broad signum (rarely absent) in form of rounded to rectangular and usually shallow pouch, with well defined line or ridge at opening commonly straight, otherwise curved. Diagnosis. Nemoria is a large and varied genus, difficult to define on external characters and resembling various species of Lissochlora and Synchlora. Moths of Synchlora are usually small with strongly bipectinate male antennae, unlike most JVemoria species. Differences in wing pattern and shape distinguish many but not all species of Liaochlora from Nemoria (see the key to genera). Nemoria also resembles Phrudocentra but that genus lacks the reddish-ringed white abdominal spots conspicuous in many species of Nemoria and rarely has the dark abdominal spots present in several other Nemoria species. Phrudocentra usually has dark markings on the under-side of the hind wings additional to those on the upper surface, unlike Nemoria, and most species of Phrudocentra have a straight or only slightly curved postmedial line on the hind wing whereas this line is usually distinctly bent or curved in Nemoria. With few exceptions, Nmoria is characterized by the well developed basal costal process of the male valva; a weakly developed process is sometimes seen in certain other genera, such as Lissochlora. The rod-like, usually long, uncus also distin<guishes Nemoria from Synchlora and from most species of LiJsochlora. The shape of the female signum separates Nemoria from the externally similar genera discussed above, except perhaps for a few species of Synchlora. Biological noles. Host-plants in the following genera were recorded by Ferguson (1 969 and 1985) for Nemoria specimens reared in North America, unless stated otherwise.

Wings without antemedial or postmedial lines; sometimes with brown terminal line; costa sometimes speckled brown. Fore wing rarely extended at apex with outer margin slightly sinuous. In a few species: outer margin of hind wing angled at vein M, or rarely at M,, occasionally very slightly scalloped, or extended to a short tail at vein M3. Venation: Sc + R, and Rs of hind wing touching but not fused. Frenulum a well developed spine in male (absent from aymanta), absent from female. Hind tibia usually with 1 (apical) pair of spurs but with 2 pairs in thalmsina group; male hind tibia without terminal extension. Abdomen with dorsal line of prominent tufts or crests on segments 2-5; larger bodied species with crests also on segments 6 and 7, smaller and paler. Crests of most species composed of broad brown outer scales and longer narrow, white or cream, central scales. Sternite 3 of male abdomen without pair of fields of modified scales (inferred from absence of enlarged scale bases) but occasionally with weak medio-posterior field. Genitalia 8 (Figs 75, 76, 1 12, 1 13, 16 1, 162) Uncus usually extremely short or without process. Socii semi-membranous and often rounded. Gnathos arms usually resemble horns, strongly sclerotized, curved and pointed, not fused in a loop. Valva often with one or more sclerotized medio-ventral processes, and sacculus often extended into a sclerotized, usually pointed process; sometimes with other processes such as small spines at the apex of the valva; occasionally with costal process. Transtilla and juxta fused to form anellar complex which usually surrounds aedeagus completely. Coremata usually absent. Aedeagus often with small cornutus and occasionally with other modifications of vesica. Abdominal sternite 8 often well sclerotized and usually extended posteriorly as two small lobes or long processes, but unmodified in a few species; without midrib. Genitalia 9 (Figs 207, 235). Apophyses anteriores short, less than one-quarter to less than half length of apophyses posteriores. Ostial surrounds variously sclerotized and modified. Ductus bursae varying in length but typically as long or longer than bulbous corpus bursae; usually lightly or strongly sclerotized and with longitudinal striations; often with sclerotized antrum. Corpus bursae usually with signum zonsisting of a narrow band which is weakly or moderately sclerotized and has a small tooth at each end that protrudes into the corpus bursae. Diagnosis. The abdominal crests composed of broad outer scales and narrow central scales distinguish most Oosjila species from other Geometrinae. The only other 'Veotropical genus which has a line of abdominal crests is Lophochorista but its crests Ire undifferentiated and it has tufts also on the thorax. In the male genitalia of Oospila.he fusion of the transtilla and juxta to form an anellar complex is characteristic, -xcept in a few species where it is reduced. This feature is not exclusively diagnostic ;ince it occurs also in Anomphax and Telotheta but the status of these genera as distinct?om Oospila is still open to question. For additional discussion involving Oospila see he diagnoses of the above genera and those of Chavarriella and Eucrostes. Pemarks. The quinquemaculata and thalassina groups differ from other Oospila species in,everal respects. They have a distinct, though still fairly short, tapered process of the Incus, the gnathos is fused as a loop with a distal tooth, and coremata are usually iresent. 3iological notes.

Whitish hind wings contrasting with green fore wings are seen also in Anomphax and the bistriaria group of Synchlora, and in certain Geometrinae outside the Neotropical Region including Chlorosea (North American) and a few North American species of Nemoria. The ennomine genus Eariodes Warren, in Brazil, also bears a close superficial resemblance to Paromphacodes. Paromphacodes is distinguished from Neotropical geometrines of similar appearance, and horn Chlorosea, in having two pairs of hind tibia1 spurs. The male genitalia of Paromphacode.? are distinct from those of all the above genera but resemble those of Lissochloru and Poecilochlora, genera which are unlike Paromphacodes in external appearance. The relationship and possible synonymy of these last two genera with Paromphacodes needs investigation. Remarks. Chrotuchlora and Narquena, known from single specimens, are here regarded as synonyms of Paromphacodes, sharing characteristics of genitalia structure and wing pattern. Distribution.

Aedeagus with spine- or finger-like, smooth or slightly serrate, subapical process; aedeagus usually with distinctly sclerotized pointed apex. Abdominal sternite 8 usually extended posteriorly as two very slight lobes with a shallow notch in between; without midrib. Genitalia 9 (Fig. 212). Apophyses anteriores more than half length of apophyses posteriores. Ostial region unmodified or with sclerotized postostial ridge and lightly sclerotized postostial plate. Ductus bursae sclerotized towards ostial end, usually becoming less so towards corpus bursae, about half to slightly more than two-thirds length of corpus bursae. Corpus bursae moderately elongate, without signum. Diagnosis. Phrudocentra is a variable genus in external appearance. The dark markings on the under-side of the hind wings additional to those on the upper surface are typical of Phrudocentra but are lacking in several species. The male genitalia are characteristic in the pear-shape formed by the distended vinculum and other structures (Figs 118, 119). Remarks. Two species here transferred from Chloractis lack a frenulum in the male but otherwise have the characters of Phrudocentra. Three species,j?accida (Figs 120, 169), tanysgs (Fig. 42) and niveiceps, are misplaced in Phrudocentra and differ from the description above, particularly in the structure of the male genitalia; jaccida and tanysps have also an unusually well developed frenulum. F jaccida and tan_ys&ys appear to be related to porphyropis, a species currently misplaced in Dichorda. They share similarities in the wing pattern (Figs 11 and 42) and in the male genitalia. P. niveiceps has similar male genitalia to those of Lissochlora and it seems to be related to that genus despite differences in external appearance. Two further species are atypical of Phrudocentra. The outer margin of the fore wing of hydatodes and uitiosa~a, particularly in the latter, is more strongly sinuous than usual. The male genitalia (examined in hydatodes) differ in several respects from those typical of Phmdocentra, for instance hydatodes has a smaller juxta which is far apart from the transtilla. Biological notes. Host-plants (known only for two species): Vochysiaceae: Voclyia fevugznea (Phrudocentra (oubnka?) in Costa Rica, specimen examined); Myricaceae: Myrica cemfera (record, and account of larva in U.S.A.: Florida presumed to be P. centmfugaria by Ferguson, 1985: 70). The larva of the unidentified species in Costa Rica has very long dorsolateral protruberances which enhance its camouflage amongst the flowers on which it feeds (Thiele, pers. comm.). Distribution. Widespread in Central and South America; [also occurring in U.S.A.: Texas and Florida]. Species. Thirty-four species. Generic placement of a few of these is uncertain. Genitalia examined: albiceps (d), albicoronata (d), assa (d), eccentrica (d), hydatodes (d), kinstonensis (d), obnubilata (d), oubrica (d), pupdata janeira (6 and 9), neis (d and 9), (8 and q), taediata (d), unidentified species (8).

Male antennae not strongly bipectinate, branches not much longer than width of flagellurn; female antennae simplc; intcrantcnnal fillet whitish. Wing pattern: ground colour green; outer margin of wings reddish brown bordered on iririer side with diffuse yellowish band; narrow diffuse white band at costa of fore wing; anternedial and postmedial lines white; under-side of hind wing predominantly whitish; discal spots absent. Wings with irrelgularly scalloped outer margins, extended partic,ularly at apex and vein M, of fore wing causing a concavity in outer margin and extended to a very slight tail at M, of angulate hind wing.

Genitalia 8 (Figs 123, 124, 172, 173). Uncus slender and rod-like, usually slightly tapered. Socii long, of similar length to uncus, very slender and slightly tapered (except rufria which has extremely large socii that are much broader than in other Rhodochlora species and have a tapered process). Gnathos a slender loop with a narrow pointed distal tooth. Valva parallel-sided or slightly tapered, often fairly narrow; often with very slight basal costal process, sometimes with slight distal process (apical in rothschildz). Transtilla often a very broad band, bilobate. Coremata absent or not noticeably developed. Aedea<gus sometimes with subapical or apical sclcrite, rarely pronounced; apex usually pointed but in a few species blunt with pair of patches of numerous small apical or subapical spines. Abdominal stcrnite 8 extended posteriorly as two lobcs, usually slight, with a V-shaped notch between (similar in most to that of Poecilochlora, Fig. 79); usually with midrib, weak or distinct. Genitalia 9 (Figs 2 15, 2 16, 237). Apophyses anteriorcs about half length of apophyses posteriores or slightly more. Ostial region unmodified. Ductus bursae membranous, slender, much shorter than corpus bursae. Corpus bursae pear-shaped, with or without signum. Diaposis. The distinctivc wing pattern, particularly the blotch between the postmcdial line and anal angle of the fore wing, and the antemedial band of the hind wing, together with the largc size of the moths (Figs 45, 46) enables recognition of Rhodochlora. The smaller Qrochlora has several similar elements of wing pattern but it difkrs from Rhodochlora in having a broad brownish band on the hind wing and posterior half of the fore wing. The yellowish base of the hind wing usual in Rhodochlora is seen also in Tachychlora but the latter has a white or green front of head, not orange or brown as in Rhodochlora. In the male genitalia the socii of Rhodochlora (Figs 123, 124) are much larger than those of Qrochlora (Fig. 12 1) or Tachychlora (Figs 128, 129). Remarks. The male gcnitalia of most Rhodochlora species are similar to Fig. 123 but rufria difkrs markedly in some respects, notably the enormous socii (Fig. 124) and also in having larger lobes on abdominal sternite 8.

Generally small moths (wing length less than I2 mm in many cases). Male antennae strongly bipectinate, tapering abruptly (length of longest autennal branches considerably more than 3 times width of flagellum at same point, esccpt in despicata). Femalc antennae simple or in a few cases slightly serrate (except jingillata in which they are bipec,tinate with shorter branches than in the male). Interantennal fillet white. Wing pattern: ground colour green, often with terminal line and sornctimes with other rcddish brown marginal markings: blotchcs or a band; discal spots sometiincs very large but entirely absent in several specics; white antemedial and postmedial lines often waved but often very indistinct. Hind wing usually similar to fore wing but in bistriaia group prcdomiriantly white or very pale grccn. Venation (Fig. 62): Sc + R, and Rs of' hind wing usually fused for a short distance but in a few species fused to nearly midway along cell; occasionally touching hut not fused. Frenulum occasionally wcak in female. Hind tibia usually with two pairs of spurs but with one, apical, pair in fingillata and hebescens and in Ncotropical and certain other species of bistriaria group. Male hind tibia with terminal extension in most species. Abdomen brown, green or whitish dorsally; majority of species with 3 or more dorsal white spots which are plain or ringed with reddish brown. Sternite 3 of male abdomen usually with pair of fields of deciduous needle-like modified scalcs, fields occasionally merging, but these absent from fringillata and bistriuria group. CMnlia d (Figs 81, 121i- 127, 174-1 76, 21 7-2 19, 238, 239). Uncus reduced (without rod-like process, cxcept in despicata which has a short rod). Socii sclerotized, tapered and pointed. Gnathos a slender loop usually with but occasionally without a narrow pointed distal tooth; occasionally modified (loop broken distally in cupedinam'a, and clc$icata has two diverging distal teeth). Valva narrow, parallel-sided or slightly tapered, usually without processes although these occur in expulsata atrafioides and

NEOTKOPICAL EMERALD MOTHS 393 despicata. Coremata usually present as dense hair-like tufts on extensible, sometimes long, membranous sac but absent or weakly developed in bistriaria group. Aedeagus with two narrow sclerotized prongs arising from proximal stem; prongs sometimes indistinct, occasionally strongly curved outwards at free end, rarely with a row of spines. Abdominal sternite 8 extended posteriorly as two small lobes with a shallow notch or scoop in between or occasionally as a single lobe; midrib usually a trace or absent but occasionally distinct. Chitalia 9 (Figs 2 1 7-2 19, 238, 239). Apophyscs antcriores usually one-third to slightly more than half length of apophyses posteriores, occasionally reduced in a Tew species. Ostial region unmodified, or with sclerotization of postostial plate or other structures. Ductus bursae often membranous or with lightly sclerotized antrum, occasionally distinctly sclerotized; very short (much shorter than corpus bursae). Corpus bursae elongate, often with bulbous anterior end, or occasionally pearshaped. With or without signum; signum, if present, usually a curved ridge or plate. Diagnosii. Sjnchlora is a large genus variable in external appearance. The histriaria group resembles Anomphax and Parumphacodes in having whitish hind wing contrasting with green fore wings (see their diagnoses for distinguishing features); the wing pattern of the ennomine genus Hemitileinopsis from Mexico is also superficially similar. The fusion of the hind wing veins Sc + R, and Rs enables most Synchlora species to be distinguished from Lissochloru and Nemoria, genera with which they could be confused. Synchlura is best characterized by the male genitalia, particularly thc reduced uncus and the rigidly sclerotized socii. 'The aedeagus shaped like a tuning fork is also a distinctive feature in most species. Xenopepla has very similar male genitalia but is strikingly different in wing pattern and shape (see Fig. 59 and the diagnosis of that genus). Kemurks. Callisteuma and CFLeteuscelis were treated as distinct from Sjnchlora because of the greater degree of fusion of the veins Sc + R, and Rs in the hind wing of the first two genera, However, the variability of this character in 5jnchlora precludes any clear cut distinction. A parallel situation exists with Hydata and its synonym Prohydata. Callisteuma and Cheteoscelis are here regarded as synonyms of Sjnchlora and the six species that were placed in Cheteoscelis are treated as the histriaria group within Synchlora. The differences between the bistriaria group and other Synchlora species, such as the whitish hind wing as opposed to the usual green colour, are no greater than those seen within Nemoria. Synchlora bi~triuta resembles the bistriaria group in fore wing pattern and is not far short of the bistriaria group in the degree of fusion of the hind wing veins Sc + R, and Rs. The female antennae of North American species of the histriaria group vary from simple to narrowly bipectinate according to Fcrguson (1985: 9 1). Males of one North American species, @nchluru faseolaria (Guenke) comb. nov., lack a frenulum. Biological notes.

Type species: Tachyp/yle acuta Butler, 1881: 329, by original designation. Ad& (Figs 53-55). Female antennae simple, serrate, or bipectinate. White interantennal fillet typically extending onto upper front of head. Wing pattern: ground colour green, in a few species with brown speckles or other markings; usually with smooth oblique white or silvery postmedial lines, antemedial absent from hind wing and often indistinct on fore wing; lines occasionally brown (waved or smooth); area between antemedial and postmedial lines sometimes lightly overlaid with white or silvery scales; wings without terminal line. Fore wing usually extended and often distinctly falcate at apex, outer margin of hind wing straight or slightly curved. Venation: Sc + R, and Rs of hind wing touching but not fused. Frenulum weak or absent from female. Hind tibia usually with two pairs of spurs but apical pair extremely small; occasionally with only one (apical) pair; usually without but occasionally with minute terminal extension. Abdomen sometimes with a few indistinct tiny white dorsal spots. Sternite 3 of male abdomen often without pair of fields of modified scales (inferred from absence of enlarged scale bases) but fields present in a few species. Genitalia 8 (Figs 83, 130, 131, 179, 180). Uncus short, commonly bifurcate or sometinies tapered to a single short rod. Socii semi-membranous and tiny. Gnathos usually a slender loop with a narrow pointed distal tooth but occasionally (allineatu and oleaster) loop incomplete and without distal tooth. Valva tapered, often strongly, usually broad at basc; with niedio-ventral process, often in the form of one or a small group of spine-like processes but in a few species mcrcly a weak ridge. Vinculum often somewhat elongated and with sides distended (as in Phrudocentra, Figs 118 & 1 19, but less pronounced). lranstilla complete or sometimes not sclerotized medially. Juxta usually large, often reaching transtilla. Coremata usually well developed as dense liair-like tufts on extensible, often long, membranous sac. Aedeagus often with

NEUIROPICAL EhlERALD MO I HS 405 one or two apical or subapical processes; processes usually spinose or serrate. Abdominal sternite 8 usually extended posteriorly as two slight lobes with a shallow notch or scoop in between, or with a single notched lobe as in Fig. 83; without midrib. Grnitalia 9 (Figs 221, 222). Apophyses anteriores about half length of apophyses posteriores or less. Ostial region with large postostial plate often heavily sclerotized, sometimes with less obvious preostial pouch. Ductus bursae usually with short sclerotized antrum but occasionally completely sclerotized, usually much shorter than oval corpus bursae but occasionally as long as this. Corpus bursae without signum. Diagnosis. The reduced apical pair of hind tibial spurs is characteristic of Tachyph_le. Slight reduction of these spurs is occasionally seen in Phrudocentra but those moths have angulate hind wings, not straight edged as in Tachyphyle. 7: nepia, a small atypical species, is exceptional iri lacking the apical pair of spurs entirely but its falcate fore wing distinguishes it from other geometrines that have only one pair of hind tibial spurs. Tacty@hyle resembles Tactyrhlol-a and a few species of Phrudorentra in wing shape. It lacks the wing pattern characteristic of Tactychlora (Figs 53-55) and the male genitalia do not form a pear shape as in Phrudocentra (Figs 118, 119) (see also the diagnoses of TacJiychlora and Phrudocentra). In the male genitalia of Tacr yle the spinelike processes of the valva and the bifurcate uncus are characteristic when these features are present. An undescribed species of Lisrochlora from Costa Rica also has a bifurcate uncus but the genitalia are very different in other respects from those of Tachyphyle. Remarks. The wings of pretiosa are heavily overlaid with white markings and the postmedial lines are strongly curved, not oblique as in most other Tachyphyle species. Speczes.

Adults (Fig. 60). Male antennae bipectinate with short branches, maximum length of branches little more than twice width of flagellum; female antennae slightly serrate or simple; interantennal fillet whitish or cream. Wing pattern: fairly thinly scaled olive or yellowish green, finely striated or mottled with diffuse whitish or transparent markings; costal margin of fore wing with transverse brown and cream striations. Antemedial and postmedial lines indistinct, waved or irregular, whitish with darker green shading on median side; discal spots darker green, indistinct (absent from some North American moths); wings without terminal line. Hind wing with very slightly scalloped outer margin, most noticeably angled at vein M,. Venation: Sc + R, and Ks of hind wing fuscd at a point or for a very short distance. Frenulum weak or absent from female. Hind tibia with one (apical) pair of spurs in male, one or two pairs of spurs in female (rnamzaria, the only Neotropical species, usually has two pairs in female but apical pair sometimes small); male hind tibia with fairly short terminal extension (very small in some Neotropical males). Hind tarsi short in male, often little more than half length of tibia, somewhat less short in female. Abdomen mottled brown with very indistinct pale spots (Neotropical species) or plain (North American species). Sternite 3 of male abdomen with pair of fields of deciduous needle-like modified scales. Genitalia 6 (Figs 135, 184). Uncus slender, rod-like and pointed. Socii slender, slightly shorter than uncus. Gnathos weakly sclerotized and incomplete, with arms not joined in a loop, not fused with tegumen; without distal tooth. Valva narrow, slightly tapered or almost parallel-sided, usually with sparse row of bristles or hairs on median ridge; median ridge sometimes prominent at base of valva with several tiny papillae. Juxta usually a narrow cone-shape. Coremata usually consist of hair-like tufts on extensible membranous sac but absent or vestigial in the type species. Aedeagus usually with fine longitudinal ridges ending in small serrations at apex. Abdominal sternite 8 more-or-less unmodified; without midrib. Genitalia 9 (Fig. 226). Apophyses anteriores short, about one-third (or often much less) length of apophyses posteriores. Ostial region with semi-membranous preostial pouch and large postostial plate (very large in the only species known from the Neotropical region). Ductus bursae membranous, usually much shorter than corpus bursae. Corpus bursae almost round, without signum. Diagnosiy. Xerochlora resembles Chlorissa, Chlorochlamys and Chloropte?yx (see also the diagnoses of those genera). It is distinguished from these by the indistinct or waved postmedial lines, together with the distinctly striated costa of the fore wing and lack

412 L hf PITRIN of terminal line. The male genitalia differ from those of Chlorochlamys and ChloroptegJx in that the basal part of the gnathos is not fused with the tegumen. Dirtrzbuhon. Predominantly in southern U.S.A. but known in Central Amcrica from Mexico, Guatemala and Costa Rica. Spfries. Five species (1 Neotropical). Genitalia examined: masonaria (8 and 9).
