Diagnosis: Winged species of mostly dark and more rarely reddish coloration.

: median lobe of aedeagus ( Figs 55–56 ) approximately 0.35 mm long; ventral process weakly curved in lateral view, apically truncate in lateral view and convex in ventral view; crista apicalis long and broad; internal sac with pair of fork-shaped apical structures (lateral view) and with a weakly curved and weakly sclerotized flagellum; apical portion of paramere ( Fig. 57 ) relatively short, barely half as long as basal portion, rather weakly dilated basally.

: spermatheca ( Fig. 58 ) with minute apical cuticular invagination.

Distribution and natural history: The distribution of O. caucasica ranges from South Ukraine and Northwest Anatolia across North Anatolia, the Greater Caucasus, and the Lesser Caucasus (including adjacent regions) to North Iran ( Maps 1 , 7 ). The record from Germany in SCHÜLKE & SMETANA (2015) is based on LOHSE (1989: 231) “nach Angaben von L. Zerche”, who reports a male from the environs of Gotha collected in 1867. This specimen was clearly either mislabelled or misidentified, as can be inferred from the revised distribution of O. caucasica .

The examined material was sifted from leaf litter, roots, moss, and bark in various forest (deciduous, coniferous, mixed) habitats and near streams. The altitudes range from 140 to 2350 m. The specimens were found in March (one record), April (2), May (26), June (27), July (37), August (1), and September (1).
