D e s c r i p t i o n: 4.3-5.1 mm; habitus as in Fig. 79 . Dark-coloured species: head and abdomen blackish, with the margins of the abdominal segments, the apex of the abdomen, and sometimes also the anterior abdominal tergites slightly paler; pronotum dark brown to blackish brown or blackish; elytra brown to dark brown; legs yellowish brown; antennae blackish brown, with the basal 2-3 antennomeres yellowish to yellowish brown.

Head weakly transverse; eyes large, at least as long as postocular region in dorsal view; puncturation very shallow, ill-defined, and moderately dense ( Fig. 80 ). Antennae of moderate length; antennomere IV approximately as wide as long; V-X transverse and of increasing width; VIII and IX approximately 1.5 times as wide as long ( Fig. 81 ).

Pronotum not very large; 1.40-1.50 times as wide as head and approximately 1.25 times as wide as long ( Fig. 29 ); maximal width in or slightly behind middle; puncturation very shallow and ill-defined; microsculpture very shallow; surface rather shiny ( Fig. 80 ).

Elytra approximately 1.2 times as wide as pronotum and at suture almost as long as pronotum; puncturation fine and dense, more distinct than that of pronotum; microsculpture shallow; surface with less shine than pronotum ( Fig. 80 ). Hind wings fully developed. Legs moderately slender; metatarsomere I of somewhat variable length, usually approximately as long as the combined length of metatarsomeres II-IV.

Abdomen slightly narrower than elytra; widest at base, gradually tapering posteriad; puncturation not very dense, decreasing in density from tergite III to tergite VIII; relatively sparse on tergite VII; posterior margin of tergite VII with palisade fringe ( Fig. 82 ); tergite VIII approximately as wide as long; posterior margin of tergite VIII weakly and smoothly convex, not concave in the middle ( Fig. 83 ).

3: sternite VIII transverse, its posterior margin broadly convex, not distinctly pointed ( Fig. 84 ); median lobe of aedeagus of similar general morphology as that of O. micans , with distinctly bent ventral process in lateral view, with two pairs of very long and massive sclerotised structures, and with ventral flagellum-like structure shaped like a fishing hook basally ( Fig. 86 ); apical lobe of paramere rather long and slender ( Fig. 87 ).

♀: sternite VIII approximately as wide as long, its posterior margin truncate in the middle ( Fig. 85 ); spermatheca with relatively short duct ( Figs 88-90 ).

E t y m o l o g y: The name (Lat., adj.) refers to the similarity to O. micans from Greece.

C o m p a r a t i v e n o t e s: From all its Turkish consubgeners, O. micantoides is best distinguished by the distinctive morphology of the median lobe of the aedeagus; in addition, it is characterised by short antennae, a relatively small pronotum (in relation to head and elytra), the weakly pronounced and shallow puncturation of the pronotum, the rather sparse puncturation of the abdomen, the transverse and posteriorly broadly male sternite VIII, and the shape of the spermatheca. From O. micans from Greece, the new species is separated by the apically more slender and more acute ventral process of the median lobe of the aedeagus, by the different shape of the long internal structures in the internal sac of the aedeagus, by the hook-like shape of the flagellum-like structure in the internal sac (in O. micans simply angled), by the more transverse, less convex (crosssection), and less distinctly microsculptured pronotum, and by the less densely punctured abdomen. For an illustration of the aedeagus of O. micans see Fig. 108.

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 was found in various localities in Mersin, Kaharamanmaraş, Adıyaman, and Antakya provinces, central southern Anatolia ( Map 6 ). The types were sifted from the litter of trees and shrubs at altitudes of 380-1580 m. In one locality in Mersin, it was collected together with O. fissa sp.n. (see below). One male collected in May is teneral.
