Figs. 38–40 , 136–141

Description. Coloration of male is typical, but lighter than in most other species, dark pattern poorly developed ( Figs. 38–39 ). Female yellow without dark spots on head, pro- and mesonotum; forewings in apical part are darkened, with partially brown veins ( Fig. 40 ).

Penis with ventral margin slightly concave (Figs. 136, 138), in disagreement with drawing from original description (Fig. 137). Lower appendage of dorsal connective bifurcated, both branches almost straight, divergent, finely serrated at the tips, upper branch distinctly longer than lower one (Figs. 138–139). Style parallel-margined, with distinct acute denticle at tip (Figs. 140–141).

Body length (including tegmina): ♂, 4.3 mm; ♀, 4.4–4.9 mm.

Differs from other Central-Asian species by shape of lower appendage of dorsal connective and style tip.

Host. Betula procurva in Tajikistan, Hissar Mtn. Range (after Korolevskaya, 1984), B. tianschanica in Southern Kyrgyzstan, Turkestan Mtn. Range (our data). It should be noted, that according to Skvortsov (1972: 27), B. procurva is a junior synonym of B. tianschanica .

Distribution. Central Asia, Hissar-Darvaz Mtn. System (Hissar and Turkestan Mtn. Ranges).

Remarks. According to original description, a part of type series is deposited in ZIN ( Korolevskaya, 1984). However, we have not found these specimens in the collection of ZIN and for this reason identification of the species is based on the original description.

The male from our material collected in Southern Kyrgyzstan on the Northern slopes of Turkestan Mtn. Range (the Valley of Layli-Mazar River 2–3 km upstream from the source of Laylyak River; Figs. 136, 138, 141) has slightly concave ventral margin of penis, but in all other respects it fits the original description ( Figs. 13 9 –140).
