Orinisobates sibiricus (Gulička, 1963)

Figs 13–19 .

MATERIAL. Numerous ♂♂, ♀♀ and juveniles ( ZMUM), E Kazakhstan, Almaty Area, Dzhungarsky Alatau Mountains, 7 km E of Lepsinsk, Chornaya River canyon, N 45°31´, E 80°43´, 1200–1400 m a.s.l., Betula , Malus , Populus etc. forest, 13–15. VI.2001, S.I. Golovatch leg.

REMARKS. This species is common and highly widespread in Central Asia ( Kyrgyzstan and eastern Kazakhstan) and western, central and eastern Siberia [ Mikhaljova, 2017]. Even though the Dzhungarsky Alatau Mountains support two species of Orinisobates Lohmander, 1933 , i.e. O. kasakstanus ( Lohmander, 1933) and O. sibiricus as refined by Enghoff [1985], the above new samples clearly represent the latter species. New illustrations ( Figs 13–19 ) are provided to document its identity and to show minor structural variations.
