Collections were made monthly during a 1-yr period (Nov Oct. 1996) during 5 days each month. A total of 2595 adult specimens were collected, belonging to 57 species, 33 genera and 8 families. Estimated richness value using the non-parametric estimator ICE was This paper is part of a long-term project to study the diversity and patterns of distribution of the fauna of insects associated with the tropical dry forest (TDF) in México (NOGUERA et al., 2002; ZARAGOZA et al., 2003). The TDF is one of the most diverse ecosystems in America and also one of the most endangered (JANZEN, 1988). In México it covers almost 8% of the country s surface and harbors a large number of endemic species (TOLEDO & OR- DOÑEZ, 1993; FLORES & GEREZ, 1994; CEBALLOS & GARCÍA, 1995). This plant community extends in a more or less continuous fashion from Sonora to Chiapas states with other intrusions in the Yucatan Peninsula and in some areas of the Gulf of Mexico (PENNINGTON & SARUKHÁN, 2005). Since 1990 only 27% of its surface has remained intact (TREJO & DIRZO, 2000). Odonata are predacious insects which do not depend directly upon plants, at least in the trophic level, as most of the other insects do. However, they use vegetation in several other ways: e. g. as breeding sites for larvae (e. g. phytotelmata

2 Odonatologica 37(4): December 1, 2008 FACTORS IN THE SELECTION OF OVIPOSITION MODE IN SYMPETRUM INFUSCATUM (SELYS) (ANISOPTERA: LIBELLULIDAE) N. ISHIZAWA Yamaguchi, Tokorozawa City, Saitama Pref., , Japan Received May 1, 2008 / Revised and Accepted June 27, 2008 The study was conducted at rice paddies in the cool temperate area of central Japan. The oviposition time period was limited to between ca 10:00 a.m. and 14:00 p.m. with a peak around noon. At an ambient temperature (Ta) below 30 o C most pairs oviposited in tandem (TO) but at a Ta above 30ºC in mid-summer most pairs separated shortly after the start of TO. The // continued to oviposit while being escorted by their partners. The regression coefficient of? body temperature (Tb) in ovipositing pairs was characteristically greater than that of the /, and it is suggested that the? is more dependent on Ta than is the /. Although the duration of oviposition was a little longer in pairs that separated after the start of oviposition, this difference was not significant. The reason why S. infuscatum starts oviposition in such a hot season of summer seems to be due to the morphological feature of its slender abdomen, which decreases abdominal light absorption at low Ta in the autumn. Sympetrum infuscatum (Selys) is one of the larger species in the genus in Japan, and the abdominal dorsum of adults is dark brown. It is distributed in Kyushu, Shikoku and Hokkaido as well as in the Mainland of Honshu. This dragonfly is seen even at heights of 2000 m above sea level in central Japan in the summer (ISHIDA et al., 1988; TSUBUKI, 1997, 2001); hence it has a migratory aspect like S. frequens (ISHIKAWA, 1985; ISHIZAWA, 1995). There are only a few fragmentary reports apart from those of WATANABE et al. (2004, 2005). S. infuscatum is known to oviposit in tandem (ARAI, 1982; ISHIDA et al. 1989). However, Mr Usui (pers. comm.) witnessed oviposition at a bog in the north of Nagano prefecture at the end of July, where pairs appeared in tandem and, as soon as oviposition started, the pairs separated and the females ovipos-

R. of China xuzaifu@scau.edu.cn Received September 1, 2007 / Reviewed and Accepted March 28, 2008 Taxonomic information is provided on the Chinese aeshnid fauna from Guangdong and Hong Kong, based on surveys completed from 1998 to Planaeschna haui sp. n. (holotype:?, Shimentai, Guangdong), P. nanlingensis sp. n. (holotype:?, Nanling, Guangdong) and P. skiaperipola sp. n. (holotype:?, Shimentai, Guangdong) are described. Periaeschna rotunda Wilson is synonymised with Cephalaeschna klotsi Asahina. Petaliaeschna gerrhon Wilson is combined with the genus Periaeschna Martin and the first / described. Boyeria karube Yokoi is newly recorded from China. Keys are provided for the determination of Oriental Brachytronini genera and identification of Chinese spp. of? Cephalaeschna Selys, Periaeschna Martin and Petaliaeschna Fraser. A total of 25 aeshnids are recorded from Guangdong, including 3 new spp., and 3 new provincial records. 12 aeshnids are recorded from Hong Kong, including Planaeschna skiaperipola sp. n. (paratype: /, Wu Kau Tang, Hong Kong). Introduction The majority of odonates examined were obtained from two sets of surveys completed between 1998 and The first set of these surveys was undertaken by teams organised by the Hong Kong based Kadoorie Farm and Botanic Garden Corporation (KFBG) between 1998 and The main collectors during these field trips were Keith DP Wilson (KW), Graham T Reels (GR), Billy Hau Chi-hang (BH) and Michael Lau (ML). The second set of surveys was under-

Box 2075, Colombo-1, Sri Lanka; 1 karoconniff@gmail.com 2 17 Monkton Avenue, Toronto, Ontario, M8Z 4M9, Canada; 1 nmgvdp@netscape.net Received July 9, 2007 / Revised and Accepted May 5, 2008 The / of E. caesia is described and figured for the first time. In earlier publications, E. caesia and E. centralis were confused with each other (cf. F.C. FRASER, 1933, The fauna of British India including Ceylon and Burma: Odonata, vol. 1, pp , Taylor & Francis, London). Amended descriptions of the? of E. caesia and of both sexes of E. centralis are provided. Key phenotypic differences between the 2 spp. are illustrated, and additional notes are given on behaviour, habitat and distribution. Elattoneura caesia was first described as Alloneura caesia by SELYS (1860) from a male specimen and was subsequently reassigned to the genus Disparoneura (SELYS, 1886). Still later, it was transfered to a new genus under the name of Elattoneura (COWLEY, 1935). LAIDLAW (1924) described the male and female of D. caesia but his description was based on specimens of D. centralis. FRASER (1933) recognized this error and described the male of D. caesia and both sexes of D. centralis and recorded the female of D. caesia as unknown. DE FONSEKA (2000) restated the information from FRASER (1933) but included, as Figure B61, the mistaken diagram of the male anal appendages from LAIDLAW (1924) 1 Figure B61 is

5 Odonatologica 37(4): December 1, 2008 DESCRIPTION OF THE LAST INSTAR LARVA OF ARGIA BARRETTI CALVERT (ZYGOPTERA: COENAGRIONIDAE) R. NOVELO-GUTIÉRREZ Departamento de Entomología, Instituto de Ecología, A.C. Apartado Postal 63, MX Xalapa, Veracruz, Mexico Received February 12, 2008 / Reviewed and Accepted March 10, 2008 The larva of A. barretti is described for the first time and compared with those of A. harknessi from Mexico and A. joergenseni from Argentina. Based upon larval characters these 3 spp. appear closely related, mainly by features such as: similar colour pattern of antennae, femora and caudal lamellae; mandibular formula; size of ligula; one palpal seta; shape of male and female gonapophyses, and the presence of claviform setae on abdominal sternite 8 and gonapophyses. Despite being one of the most speciose odonate genera in the New World (about 110 species [GARRISON, 1994]), not much work was done with the immature stages of Argia Rambur during the last 15 years. The larvae of only five species were described in this period, viz. A. pima Garrison and A. sabino Garrison (HOEKSTRA & SMITH, 1999), A. funcki (Selys) (NOVELO-GUTIÉRREZ & GÓMEZ-ANAYA, 2006), A. adamsi Calvert (DE MARMELS, 2007), and A. joergenseni Ris (VON ELLENRIEDER, 2007). WESTFALL & MAY (1996) keyed some species but without providing a formal description. In this paper, I describe and illustrate the previously unknown last instar larva of A. barretti Calvert.

6 Odonatologica 37(4): December 1, 2008 CALICNEMIA ZHUAE SPEC. NOV. FROM SHAANXI, CHINA (ZYGOPTERA: PLATYCNEMIDIDAE) H.-j. ZHANG and Z.-d. YANG Shaanxi Bioresource Key Laboratory, Shaanxi University of Technology, Hanzhong , Shaanxi, China Received January 31, 2008 / Revised and Accepted September 5, 2008 Both sexes of the new sp. are described and illustrated. Holotype? and allotype /: China, Shaanxi prov., Langao co., Mt Dubashan, alt m, 28-VII-2006; both deposited with the Shaanxi Bioresource Key Laboratory, Hanzhong, China. The pattern of the head and synthorax are similar to C. miles (Laidl.), from which the new sp. differs in pattern of the top of the abdomen and in the structure of anal appendages and penile organ. The genus Calicnemia Strand is confined to Asia and its distribution is centred in the Himalaya range. Most species occur in the montane forest habitats. So far, 8 species have been reported from China and were recently reviewed by Yu & Bu (2008), viz. C. chaoi Wilson, C. erythromelas (Sel.), C. eximia (Sel.), C. gulinensis Yu & Bu, C. haksik Wilson & Reels, C. miles (Laidlaw), C. porcata Yu & Bu, and C. sinensis Lieftinck. The specimens of the new species were collected by our students, Mo Fa-xiang and Wang Hao-jie, from the Dabashan mountain, located S of Mt Qinling in central Shaanxi, on the border between the northern temperate zone and the cool subtropical zone, i.e., on the border between the Palaearctic and Oriental biogeographical regions. The Dubashan mountain is actually situated within the Oriental Region. Calicnemia zhuae sp. n. may be a species with the northernmost distribution for the genus.
