Folsomia candida Willem, 1902 sensu lato

Discussion. Our specimens fit to diagnosis of ' F. candida sensu lato' proposed by Potapov & Gao (2012). They are more similar to F. stella sensu Fjellberg by having few chaetae on manubrium but differ from two forms of this species known in Northern Europe ( Fjellberg, 2007). The specimens from Buryatia are large, have 3+3 anterior chaetae on manubrium, 3–5+3–5 chaetae on ventrum of Th.III, more than 2 sensilla on Ant.I, up to 12+12 laterodistal chaetae on VT, and a conically pointed abdominal tip in epitoke males.

Distribution and ecology. Known from two localities: Khamar Daban Range and Vitim Plateau ( Fig. 1 : loc. 1, 9). In the former it was abundant under looser bark.
