ABSTRACT. Folsomia kuznetsovae sp.n. is described from forest zone of European part of Russia, Ukraine and Scandinavia. It is closely related to F. bisetosa Gisin, 1953 and differs by presence of ml1 setae on manubrium, fewer setae on body tergites and foil setae missing on last abdominal segment. The distribution map of two species in Palearctic is given. In Asia F. bisetosa is distributed in Arctic and boreal regions but is limited to the Arctic in Europe; F. kuznetsovae sp.n. takes the corresponding biotopes of the former species (damp and oligotrophic sites) in forest zones of Europe.
