Material examined.

1 male (IBSS), site 9; 3 males (ASU), site 16; 1 male (ASU), site 18.

Distribution.

This species is characterized by disjunctive area. The first distribution area is in the south of Siberia (Republic of Altai, Republic of Khakassia, southern part of Krasnoyarsk Province, Republic of Tyva) and the second one spreads in the Russian Far East (Maritime Province, southern part of Khabarovsk Province, Amur Area, Jewish Autonomous Area) and North-Eastern China.

Remarks.

This species is characterized by euryoky, dwelling in Siberia in herbaceous meadows, small-leaved, mixed and dark coniferous forests, and subalpine meadows and montane tundras, up to 2500 m a.s.l. ( Mikhaljova and Nefediev 2003). In the Kyga Biogeocenosis Profile the species is very rare (0.5-1.5 ind./m2), collected from the mid-mountain dark coniferous forest, and also from subgoltsy sparse growths of Pinus sibirica and mountain tundra with dwarf bushes of Betula rotundifolia and Salix glauca , with the maximum altitude registered is about 2194 m a.s.l.
