Material.

Far East of Russia, Magadanskaya Region, Ten’kinsky District, village Kulu, 04.ix.1995, coll. S. Bukhkalo.

Nevertheless, F. brevisensilla does not possess several unique characteristics of the latter species, e.g., large and tubular accp3-s on Abd.V and the absence of subapical seta on posterior side of dens.

Distribution.

It is the most northern species of the ' inoculata ' group since known so far only in the basin of Kolyma River (NE Asiatic part of Russia).
