Oxypoda collaris SAULCY 1865: 633 .

Type material examined: Holotype ♀ [dissected prior to present study]: Jerusalem / Ox. collaris / Ox. collaris Scy Type unic. / Holotypus / Muséum Paris Coll. Abeille de Perrin / Oxypoda collaris Saulcy holotype M. Tronquet dét. 1998 / Oxypoda collaris Saulcy det. V. Assing 2006 ( MNHNP).

Additional material examined: see ASSING (2003, 2004b, in press).

R e d e s c r i p t i o n: 4.5-6.0 mm; habitus as in Fig. 172 . Coloration: head blackish; pronotum dark brown to blackish; elytra pale yellowish brown, with the area near scutellum and often also the postero-lateral angles more or less extensively infuscate, dark brown to blackish, the central black spot forming an inverted triangle including the scutellum, antero-laterally extending to – but not including – humeral angles, and posteriorly usually extending along suture almost to posterior margin; dark spot in postero-lateral angles often indistinct or even absent; abdomen dark brown to blackish, with the posterior margins of the segments and the apex somewhat paler; legs yellowish brown, with the femora sometimes more or less extensively slightly infuscate; maxillary palpi brown; antennae dark brown.

Head 1.05-1.10 times as long as wide ( Fig. 173 ); puncturation moderately dense and shallow; integument with distinct microreticulation; eyes large ( Fig. 174 ), almost as long as postocular region in dorsal view. Antennae very long and slender ( Fig. 175 ), all an- tennomeres longer than wide; antennomere XI with weakly pronounced sexual dimorphism, in 3 usually about as long as the combined length of VIII-X, in ♀ usually slightly shorter.

Pronotum very slender, weakly transverse, approximately only 1.1 times as wide as long and 1.25-1.30 times as wide as head; maximal width in – or a short distance anterior to – middle; puncturation as shallow as that of head, but distinctly denser; microsculpture as pronounced as that of head ( Fig. 173 ); hypomera distinctly visible in lateral view.

Elytra approximately 1.3 times as wide as pronotum and at suture as long as or slightly shorter than pronotum; puncturation very dense and sometimes weakly granulose, much coarser than that of pronotum; microsculpture indistinct ( Fig. 173 ). Hind wings fully developed. Legs very slender; metatarsus slightly longer than metatibia; metatarsomere I approximately as long as the combined length of metatarsomeres II-IV.

Abdomen distinctly narrower than elytra; widest at segments III/IV, gradually tapering posteriad; puncturation very fine and very dense, not noticeably sparser on tergite VII than on tergite III; posterior margin of tergite VII with palisade fringe ( Fig. 112 ); tergite VIII weakly oblong, its posterior margin strongly convex (similar to Fig. 217 ), without sexual dimorphism.

3: sternite VIII approximately as long as wide, its posterior margin distinctly projecting in the middle and sharply pointed ( Figs 207-208 ); median lobe of aedeagus as in Figs 176-179 , ventral process apically bifid in ventral view; apical lobe of paramere as in Fig. 209 .

♀: sternite VIII approximately as long as wide, its posterior margin convex or indistinctly angled in the middle ( Fig. 210 ); spermatheca somewhat variable ( Figs 211-213 , 226 ).

C o m p a r a t i v e n o t e s: Oxypoda collaris is distinguished from all its Western Palaearctic congeners by external characters alone, especially by the highly distinctive slender pronotum, as well as by the long and slender legs and antennae. In addition, it is separated from similar species of the subgenus Oxypoda by the morphology of the aedeagus. For more details on distinguishing characters separating it from similar syntopic species see the (re-)descriptions below.

D i s t r i b u t i o n: This distinctive species has become known only from the surroundings of Jerusalem (type locality), and from central southern Anatolia ( Map 9 ). For details regarding the records from Turkey see ASSING (2003, 2004b, in press).
