Folsomia sp.

Discussion. Our specimens resembles F. vasilyevi Berezina & Potapov, 2006 (W Siberia) and F. obscurocellata Potapov & Cassagnau, 2000 ( Nepal) . One ocellus is shared with the former species while abundant chaetotaxy of anterior side of furca (11–13+11–13 on manubrium and 18–19 chaetae on dens) indicates the similarity with the latter one. A similar form was found by us in the Amur area.

Distribution and ecology. Known only from a few sites in the W Khamar Daban Range ( Fig.1 : loc. 9).
