Male brown, usually with traces of dark pattern on face, pro- and mesonotum, forewings brown, darker in apical part ( Fig. 41 ). Female similar to male or yellow ( Figs. 42–43 ). Penis of typical shape, with ventral margin convex or almost straight in side view (Figs. 142-143). Lower appendage of dorsal connective with rather long base, bifurcated, upper branch almost twice as wide and long as lower one. Both branches more or less straight, parallel to each other or slightly bent inwards, with margins finely serrated (Figs. 143–145). Style parallel-margined, with acute tip (Figs. 146–147). Body length (including tegmina): ♂, 4.0– 4.5 mm ; ♀, 4.5–4.8 mm . Nymph brown with pale yellow basal and middle segments of abdomen ( Fig. 44 ) or entirely pale yellow. Diagnosis . Distinctly differs from O. obstructa and O. tadzhica by coloration and shape of lower appendage of dorsal connective. Somewhat similar to O. ivanovae , but differs in male coloration ( Figs. 38 and 41 ) and in shape of lower appendage of dorsal connective (branches divergent in O. ivanovae , parallel or bent inwards in O. abdykulovi ) and style tips (with denticle in O. ivanovae , simple acute in O. abdykulovi ). Moreover, these two species apparently are allopatric: O. ivanovae occurs in Hissar-Darvaz, O. abdykulovi in Tien Shan. In the shape of male genitalia similar to O. alni , but differs in coloration, size, host and distribution. In shape of lower appendage of dorsal connective similar to O. flavicollis species group, but has another shape of penis. Host. Betula tianschanica . In the Kekemeren River Gorge was collected together with O. obstructa . Calling signal. Signal is a phrase lasting from 4–5 up to 15–20 s ( Figs. 121–122 ). Phrase consists of syllables following each other with a period about 200–270 ms at 19–20o C ( Fig. 123 ) and about 120–170 ms at 26–29o C ( Fig. 124 ). Distribution. West and Central Tien Shan (Chatkal and Ferghana Mtn. Ranges, Kekemeren River Valley). Etymology. This species is named after Asek Abdykulov (Kara-Balty, Kyrgyzstan ), my best friend in Kyrgyzstan and driver in all my expeditions to Central Asia.
