Figs. 36–37 , 132–135

Description. Coloration typical, but rather light, brown ( Figs. 36–37 ).

Penis with ventral margin almost straight in side view and with side margins serrated in ventral view, abruptly tapering in apical third, with narrow tip (Figs. 132–133). Bifurcated part of lower appendage of dorsal connective very wide, in shape of open-end ring, both branches narrow, lower branch about twice as long as upper one (Fig. 133). Style strongly expanded in apical third, with broad angulate tip (Fig. 134), somewhat twisted along axis so that extension in the upper third is not visible in broadest aspect i.e. in flat preparation (Fig. 135).

Body length (including tegmina): ♂, 4.0 mm; ♀, 4.2 mm.

In shape of male genitalia somewhat similar only to O. obstructa (see the same section in the description of the latter species).

Host. Betula turkestanica ; according to Skvortsov (1972: 27), this species is a junior synonym of B. tianschanica .

Distribution. Known only from the type locality: Ramit Gorge, Hissar Mtn. Range, Tajikistan.

Remark. Known only from the type series, the above description is based on male holotype and female allotype deposited in ZIN.
