D e s c r i p t i o n: 3.2-4.0 mm; habitus as in Fig. 28 . Light-coloured species: head brown to dark brown; pronotum, elytra, and abdomen yellowish brown to reddish brown, with the central parts of tergites III-V, most of tergite VI, and the anterior half of tergite VII more or less distinctly infuscate; legs yellowish; antennae brown, with the basal 3 antennomeres paler.

Head approximately as wide as long; puncturation dense, very fine, shallow, indistinct; microsculpture distinct ( Fig. 29 ); eyes moderately large ( Fig. 30 ), weakly projecting from lateral outline of head, distinctly shorter than postocular region in dorsal view. Antenna of moderate length, antennomere X approximately 1.5 times as wide as long ( Fig. 31 ). Preapical joint of maxillary palpus slender, more than 3 times as long as wide.

Pronotum 1.40-1.50 times as wide as head and approximately 1.20-1.25 times as wide as long ( Fig. 29 ); maximal width in or slightly behind middle; puncturation very dense, fine, but less so than that of head; microsculpture shallow, less distinct than that of head; surface with little shine.

Elytra slightly wider than pronotum and at suture approximately 0.8 times as long as pronotum; puncturation fine and dense, more distinct than that of pronotum; microsculpture indistinct; surface with more shine than pronotum. Hind wings of somewhat reduced length, but longer than elytra (in those specimens whose hind wings were examined). Legs moderately slender; metatarsomere I long, longer than combined length of metatarsomeres II-IV.

Abdomen at base approximately as wide as elytra or slightly narrower; widest at segments III/IV, segments V-VIII gradually tapering ( Fig. 28 ); puncturation extremely fine and very dense, as dense on posterior as on anterior tergites; microsculpture shallow; posterior margin of tergite VII with palisade fringe.

3: sternite VIII oblong, its posterior margin pointed in the middle ( Figs 32-33 ); median lobe of aedeagus shaped as in Figs 36-37 ; apical lobe of paramere rather long, with short apical, long thin intermediate, and two long basal setae ( Fig. 39 ).

♀: sternite VIII oblong, its posterior margin concave in the middle and with modified stout marginal setae ( Figs 34-35 ); spermatheca as in Fig. 39.

E t y m o l o g y: The name (Lat., adj.) is derived from the name of the mountain range, where the type localities are situated.

C o m p a r a t i v e n o t e s: From the similar O. abdominalis and O. kartabensis , the species is distinguished especially by the morphology of the primary sexual characters (large crista apicalis, shape of ventral process of aedeagus, shape of spermatheca). From the former, it is additionally separated by the more distinctly punctate pronotum, the somewhat more massive antennae, the slightly smaller eyes, and the usually less distinctly bicoloured body. From the latter, it is also distinguished by the slightly smaller eyes, the shorter elytra, and the shorter hind wings.

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 species is currently known only from the Ziyaret Dağı in southern Antakya province, central southern Anatolia, not far from the Syrian border ( Map 1 ). The types were sifted from the litter of shrubs (oak, laurel) at an altitude of 760- 930 m. Three specimens collected in the beginning of April are teneral.
