A new species and faunistic records of Amarygmus from the Northern Moluccas (Coleoptera: Tenebrionidae: Amarygmini) HANS J. BREMER Abstract A new species, Amarygmus ventricosus n. sp. (Coleoptera: Tenebrionidae: Amarygmini) from the Northern Moluccas/Indonesia (Morotai and Halmahera), is described and illustrated. Faunistic records of eight other species of Amarygmus from the Northern Moluccas are given. K e y w o r d s : Coleoptera, Tenebrionidae, Amarygmus, new species, Northern Moluccas, faunistic records. Zusammenfassung Eine neue Art, Amarygmus ventricosus n. sp. (Coleoptera: Tenebrionidae: Amarygmini) von den nördlichen Molukken/Indonesien (Morotai und Halmahera) wird beschrieben und abgebildet. Funddaten von acht anderen Amarygmus-Arten von den nördlichen Molukken werden aufgelistet. Contents 1 Introduction Morphometry Description of the new species Records of other species of Amarygmus from the Northern Moluccas References Introduction The Northern Moluccas consist mainly of the Indonesian islands of Halmahera, Ternate, Bacan und Morotai. The Tenebrionidae of that archipielago, including species of the genus Amarygmus Dalman, 1823, are insufficiently known. This is probably due to insufficient collecting activities. PIC (1915) described Amarygmus batjanensis (Pic, 1915) [syn. A. testaceicornis (Pic, 1915)] from the Northern Moluccas. GEBIEN (1920) reported the occurrence of A. cuprarius iodicollis Guérin-Méneville, 1830 from Ternate, Bacan, Halmahera and Watubella Islands, and of A. orientalis (Fairmaire, 1883) from Bacan. BREMER (2003, 2008) described A. grimmi Bremer, 2003 from Halmahera and A. venetus Bremer, 2008 from Bacan and Halmahera. Considering the great number of species of Amarygmus on the neighbouring islands of Sulawesi and the Central and Southern Moluccas, it would be surprising that the islands of the Northern Moluccas should have fewer species. During the past years A. RIEDEL, A. SKALE and A. W EIGEL used short stays on these islands to collect some Tenebrionidae. Due to their activities one new Amarygmus was collected which is described in this paper. A second, probably new species is severely damaged so that I cannot describe it. In addition, collection data of Amarygmus of this area are presented, which were determined by me during the last years. It is highly probable that systematic collections on these islands would considerably increase the number of tenebrionid species (including Amarygmus).

(Fig. 1A H) Holotype ( ): Indonesia, Maluku, Is. Morotai, W Daruba, Raja, 19.XI.1999, m, leg. A. RIEDEL (SMNS). P a r a t y p e s : Indonesia, Halmahera NW, 21 km N Jailolo, Goal Village, 100 m, 1 14'11"N '10"E, 23.I.2006, leg. A. SKALE, plantage, river side (1 CS, 1 ZSMB) (both paratypes more or less damaged). Etymology Ventricosus (Lat.) = big-bellied. Diagnosis Small, winged; with a small pronotum and broad elytra. Head, pronotum and elytra black, this colouration is contrasting with the yellowish brown legs. Elytra with rows of medium-sized punctures. Width of frons medium; antennae long. A. ventricosus resembles in size and shape A. caelebs Bremer, 2004 (BREMER 2004b: 50 52) from northern Sulawesi. However, A. caelebs is wingless while A. ventricosus possesses wings; A. caelebs has striae on the elytra, A. ventricosus rows of closely set punctures; the antennae of A. caelebs are long, but in A. ventricosus the antennomeres are longer and more slender than in A. caelebs; frons and clypeus of A. caelebs are less densely punctured than in A. ventricosus. Description M e a s u r e m e n t s : Body length mm; body width mm. Ratios: Pronotum: width/length ; width hind corners/width front corners Elytra: length/width ; length elytra/length pronotum ; maximum width elytra/maximum width pronotum C o l o u r a t i o n : Head, pronotum and elytra black and slightly opaque; legs and antennomeres 1+2 yellowish brown, antennomeres 3 11 dark brown to black. Underside dark brown, its colouration contrasting with the yellowish femora. H e a d : Frons of median width; width corresponding to length of antennomere 3; with indistinct, small punctures. Genae raised, anteriorly terminating at the level of the fronto-clypeal suture. Fronto-clypeal suture slightly incised, bent. Clypeus stretched forwards, somewhat convex; size and density of punctures on clypeus similar to those on frons. P r o n o t u m : Relatively narrow, markedly convex transversely and longitudinally. Sides bent, with maximum width in the middle, narrowing towards the rounded hind corners and the acute front corners. Anterior margin excavated. Sides and anterior margin bordered. Lateral margins in dorsal view very narrowly visible only in the posterior halves. Front corners rectangular in lateral view, hind corners clearly obtuse. Surface with indistinct, sparse, tiny punctures. S c u t e l l u m : Triangular, without punctures. E l y t r a : Ovate, markedly convex. Maximum height and width somewhat anterior to middle. Shoulders not prominent. Apices of elytra mutually rounded. Lateral edges in dorsal view visible only at shoulders and apex. With rows of medium-sized punctures which are sometimes situated in slightly impressed rows; in row 4 approximately 42 punctures; punctures of the rows indistinct at the apex. Intervals either slightly convex or flat, with tiny, sparse punctures. P r o s t e r n u m : Short. Anterior margin continuously bent upwards. Apophysis short, slightly longer than wide (2.4 : 1.8); lateral margins rounded and raised ventrad; median space in between with a relatively broad and deep groove; apex straight, surface with some short hairs. M e s o s t e r n u m : Anterior margin scarcely excavated in the middle; covered with medium-sized punctures and short hairs. M e t a s t e r n u m : Anterior half with closely set medium-sized punctures, posterior half with much smaller punctures. Medium line slightly incised. S t e r n i t e s : Disc of sternite 1 with a few small punctures; sternites 2 5 with a few, extremely small punctures. Sternite 5 apicomedially without sexual characters in the males. A n t e n n a e : Very long, reaching posterior fourth of elytra. Length/width ratio of antennomeres 1 11 equals to 20:8 / 8:6 / 22:6 / 16:6 / 20:6 / 17:6 / 20:6½ / 22:6½ / 20:7 / 20:7 / 23:8. L e g s : Relatively long. Femora slightly thickened towards the second third. Pro- and mesotibiae approximately straight; metatibiae straight but their apical fifth slightly incurved. Protarsomeres 1 3 slightly widened and prolonged in males. Lengths of protarsomeres 1 5 in a male as 10:9:7:6:23, lengths of mesotarsomeres 1 5 as 13:9:7:6:23, lengths of metatarsomeres 1 4 as 38:14:5:22. A e d e a g u s : See Fig. 1F H.

4 136 STUTTGARTER BEITRÄGE ZUR NATURKUNDE A Neue Serie 3 Remarks A similar specimen from Bacan Island [ N.-Molukken, Bacan, 10 km E Labuha, 120 m, 0 38'07"N '48"E, 14.I.2006, leg. A. SKALE, UWP + plantage ] possesses slightly longer elytra and is more lustrous. Unfortunately, this specimen is very damaged. Therefore, I cannot decide whether it is a subspecies or a variety of A. ventricosus n. sp. 4 Records of other species of Amarygmus from the Northern Moluccas The data on the labels are given in the original language and with the abbreviations used by the collectors.

Remarks This is a small, elongate species which was previously known only from Ceram (Central Moluccas). The specimens from Halmahera are smaller in average than those from Ceram, but I do not recognize other characters which could separate them. Unfortunately, all specimens from Halmahera and from Ceram are females, therefore the aedeagi remain unknown. The size of the punctures of the striae and maximum width of the elytra are relatively heterogenous within the specimens from Halmahera. Body length of the specimens from Ceram mm, body width mm. Body length of the specimens from Halmahera mm, body width mm. Amarygmus grimmi Bremer, 2003 H a l m a h e r a : NE Halmahera, Umg.
