Folsomia vtorovi Martynova, 1971

Discussion. A species of F. taimyrica complex (' quadrioculata ' group) which is defined by the combination of reduced ms formula (10/100) and the absence of ocelli and median macrochaetae on Th.III. Specimens from Buryatia have longer macrochaetae than in typical populations of F. v t o ro v i (Central Asia).

Distribution and ecology. A rare species occurring in damp forests ( Fig. 1 : loc.1, 4). In Siberia the species is probably widely distributed, but contrasting ecological and morphological data indicate that several species are covered by the name F. v t oro v i.
