D e s c r i p t i o n: 3.7-4.4 mm; in external morphology highly similar to O. fissa , but distinguished as follows:

Head and pronotum with - on average - more distinct puncturation and more distinct microsculpture, integument less shiny. Pronotum on average slightly more transverse and less convex. Elytra with more pronounced puncturation ( Fig. 142 ).

3: sternite VIII weakly oblong, its posterior margin strongly convex ( Fig. 143 ); median lobe of aedeagus of similar general morphology as in O. fissa , but ventral process more strongly bent, slightly longer, and apically not incised, crista apicalis smaller, and inter-

nal structures of different shape ( Figs 145-147 ); apical lobe of paramere as in Fig. 148 .

♀: sternite VIII weakly oblong, its posterior margin moderately convex ( Fig. 144 ); spermatheca of very variable shape ( Figs 149-150 )).

E t y m o l o g y: The name (Lat., adj.: straight) refers to the weakly pronounced internal structures of the aedeagus.

C o m p a r a t i v e n o t e s: From the similar O. fissa and O. recta , the species is separated by the - on average - more distinct puncturation of the forebody, the slightly more transverse and less strongly convex pronotum, and by the morphology of the aedeagus.

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 known from several localities in Kahramanmaraş, Antakya, and Gaziantep, central southern Anatolia ( Map 7 ). The holotype and the syntopic paratypes were sifted from litter of shrubs and from grass in a cultivated area ; for a photograph of this locality see figure 1 in ASSING (2004c). The altitude of the type localities range from 750 to 1120 m. Some of the type specimens collected in April are teneral.
