Folsomia continentalis Potapov & Dunger 2000
No full textFolsomia continentalis Potapov & Dunger, 2000 Discussion. A species of F. taimyrica complex (' quadrioculata ' group) which is defined by the combination of reduced ms formula (10 / 100), the presence of clear ocellus and the absence of median macrochaetae on Th.III. Specimens from Buryatia are paler than typical specimens (Mongolia). Distribution and ecology. In Buryatia, the species occurs in south areas (Selenga Low Plateau, Khamar Daban, Turka). It was described from Mongolia and recorded in Tuva and Chita region (Stebaeva et al. 2001, Dunger & Potapov 2000), it may possibly occur further north as it was found in NE European part of Russia (Babenko 2012) where it is obviously very rare. In Buryatia it inhabits dry larch forests and is common in the Zagansky Range (Fig. 1: loc. 3, 9, 15).Published as part of Potapov, Mikhail & Gulgenova, Ayuna, 2013, Isotomidae (Collembola) of Buryat Republic.

Folsomia atropolaris Potapov & Babenko 2000
No full textFolsomia atropolaris Potapov & Babenko, 2000 Discussion. A characteristic species of F. regularis complex (' quadrioculata ' group) due to 3 + 3 laterodistal chaetae on VT and basal ms on Ant.III missing. In the Arctic this species is usually mottled grey or even almost black while the specimens from Buryatia are less pigmented. They also never have ocelli which are often present (rudimentary) in the northern populations. The place of the missing ocellus is always well marked by dark pigmentation. In the Northern Barguzin Range another, probably new species, closely related to F. atropolaris, was collected. It has no basal ms on Ant.III (shared with F. a t ro p o l a r i s), 4 + 4 laterodistal chaetae on VT (vs. 3 + 3 in F. atropolaris), and shows very characteristic chaetotaxy of anterior side of manubrium with 3 + 3 chaetae arranged as 1 + 1 subapical and 2 + 2 in more proximal part. More material is needed to describe this new species. Distribution and ecology. A rather common species in larch taiga forests at the upper flow of the Barguzin River (Northern Buryatia) (Fig. 1: loc. 8), especially on damp and cold slopes. The species is widely distributed in Siberia but so far does not occur in southern areas (Babenko & Fjellberg 2006).Published as part of Potapov, Mikhail & Gulgenova, Ayuna, 2013, Isotomidae (Collembola) of Buryat Republic.

Folsomia villosa Potapov & Marusik 2000
No full textFolsomia villosa Potapov & Marusik, 2000 Discussion. Our material resembles to the morphology of specimens in populations of F. villosa from Far East Russia. Colour varies from white (more common) to lightly spotted due to scattered pigment grains. Such a variability is present both in Siberia and the Far East. Anterior chaetae on manubrium vary wider than it was given in the first description: from 5 + 5 to 7 + 7 (vs. 6 + 6). In the Far East the species appears to occur in two forms: with 4 + 4 and 3 + 3 basolateral chaetae on posterior side of manubrium, the former has thinner chaetae on anterior half of dorsum of Abd.IV. In Buryatia, only the latter form is found. In the N Barguzin Range and Vitim Plateau a closely related form/species was found which differs from F. villosa by shorter macrochaetae and fewer chaetae on anterior side of manubrium and dens (4 – 3 + 4 – 3 and 8–9, respectively). The difference makes this form very similar to F. re g u l a r i s Hammer and related species which, in contrast, have ocelli. The form is sometimes mixed with common F. v i l l o s a but notably prefers drier sites, including steppes. Distribution and ecology. So far the species was recorded in three localities of the Far East of Russia and Buryatia (Potapov & Marusik 2000, Chimitova et al. 2010). After the inclusion of our data the distribution of this species area is better understood: it is widely distributed in the south of E Siberia and the Far East of Russia (Fig. 23), the formal gap between Buryatia and Far East probably results from insufficient knowledge on the Chita and Amur regions. In Buryatia the species occurs in northern and eastern areas. No records are known in the west of Buryatia (Khamar Daban and Tunkinskiye Gol'tsy) where it is possibly replaced with F. sensivillosa sp. nov. This is one of the most common species in Buryatia (Fig. 1: loc. 1, 2, 3, 5, 7, 8). Prefers different kinds of taiga forest and does not penetrate to steppes and the alpine zone. In the dry Selenga Low Plateau (south) it seems to be limited to damp places while it is more eurytopic in humid mountains. The ecological preferences in Vitim Plateau are described in Chimitova et al. (2010).Published as part of Potapov, Mikhail & Gulgenova, Ayuna, 2013, Isotomidae (Collembola) of Buryat Republic. II.
