Materials of Hypogastruridae, Odontellidae, Neanuridae, Onychiuridae and Isotomidae from East Africa were studied. Several new species are described: Acherontiella kowalskiorum sp. n., Furculanurida grandcolasorum sp. n., Stachorutes dallaii sp, n., and Paleonura cassagnaui sp, n. Friesea vrorovi Tshelnokov, 1977 and Tullbergia kilimanjarica (Delamare Deboutteville, 1953) are redescribed. Stachorutes arlei (Thibaud & Massoud, 1980) is a new combination. Identification keys for Friesea Dalla Torre, 1895 with 2 + 2 eyes and Stachorutes Dallai, 1973 are given.
This paper deals with the taxonomy and distribution of Folsomia species from northern Russia with special reference to the Asian regions. Eight new species are described: F. amplissima sp. n., F. ancestor sp, n., F. atropolaris sp. n., F. borealis sp. n., F. brevisensilla sp. n., F. cryptophila sp. n., F. longidens sp. n., F. palaearctica sp. n. Five species, F. taimyrica, F. regularis, F. sp. aff. altamontana, F. alpha, and F. janstachi (nom. n. for Isotomina gracilis Stach, 1962 nec Folsomia gracilis Latzel, 1922), are redescribed. F. binoculata (Wahlgren) has been recovered and redescribed. The positions of F. macrochaetosa, F. magadani, and F. tesari have been defined more exactly on the basis of type material. An identification key of the northern Asiatic species of the genus is given.
