D e s c r i p t i o n: 2.4-3.0 mm. Usual coloration: blackish brown, with the pronotum, the elytra, the posterior margins of the abdominal segments, and the abdominal apex slightly paler, dark brown; legs light brown; antennae dark brown, with the basal 2-3 antennomeres somewhat paler; occasionally, the body may be of darker or of slightly paler coloration. Habitus as in Fig. 17 .

Head approximately as wide as long; puncturation fine, shallow, indistinct; microsculpture shallow, but distinct ( Fig. 18 ); eyes moderately large ( Fig. 19 ), weakly projecting from lateral outline of head, slightly shorter than postocular region in dorsal view. Antenna as in Fig. 20 , antennomere X approximately 1.5 times as wide as long. Preapical joint of maxillary palpus approximately twice as long as wide.

Pronotum 1.35-1.40 times as wide as head and approximately 1.30 times as wide as long ( Fig. 18 ); maximal width in or slightly behind middle; puncturation fine, but less so than that of head, dense, and shallow; microsculpture shallow, but distinct; surface with little shine.

Elytra slightly wider than pronotum and at suture approximately as long as pronotum; puncturation fine and dense, usually slightly more distinct than that of pronotum; microsculpture distinct; surface mostly with somewhat more shine than pronotum. Hind wings fully developed. Legs moderately slender; metatarsomere I long, as long as or even longer than combined length of metatarsomeres II-IV.

Abdomen slightly narrower than elytra; widest at segments V / VI, segments VII-VIII weakly tapering ( Fig. 17 ); puncturation extremely fine and very dense, slightly less dense on posterior than on anterior tergites; microsculpture shallow; posterior margin of tergite VII with palisade fringe.

3: sternite VIII approximately as long as wide, its posterior margin pointed in the middle ( Fig. 21 ); median lobe of aedeagus shaped as in Figs 23-25 , ventral process distinctly angled in lateral view, internal structures of highly distinctive shape; apical lobe of paramere rather long, with short apical, long thin intermediate, and two long basal setae ( Fig. 26 ).

♀: sternite VIII transverse, its posterior margin broadly convex ( Fig. 22 ); spermatheca as in Fig. 27.

E t y m o l o g y: The name (Lat., adj.) refers to the resemblance of the subapical structures of the aedeagus with a cockscomb.

C o m p a r a t i v e n o t e s: Among the Eastern Mediterranean congeners, Oxypoda cristata is most similar and also most closely related to O. moreatica SCHEERPELTZ from Greece, a conclusion suggested by the similarly derived morphology of the aedeagus. From this species, O. cristata is reliably distinguished only by the primary sexual characters, i. e. the distinctly angled ventral process and the internal structures of the aedeagus, as well as the shape of the spermatheca.

D i s t r i b u t i o n a n d b i o n o m i c s: The known range of the species extends from northeastern Greece to central southern Anatolia. It is apparently not very rare in southern Anatolia from Muğla in the west to Kahramanmaraş in the east ( Map 2 ). It is was mostly sifted from leaf litter in various forested and unforested biotopes, at a wide range of altitudes, from 150 m to 1850 m. A dissected female collected in July had a mature egg in the ovaries.
