The paper considers blind species of the genus Folsomia having two pairs of macrosetae on both meso- and metathorax and united in so-called ‘inoculata’ group, which is given a new, more laconic definition. Morphological characters important in the group’s taxonomy are discussed and a further division into four subgroups is proposed. Eight new species, i.e., F. amurica Potapov & Kuznetsova, sp. n., F. breviseta Potapov & Kuznetsova, sp. n., F. calcarea Potapov, sp. n., F. imparis Potapov & Hasegawa, sp. n., F. laconica Potapov & Kuznetsova, sp. n., F. tertia Potapov, sp. n., F. trisensilla Potapov, sp. n., and F. tubulata Potapov & Babenko, sp. n., are described. F. hidakana Uchida & Tamura and F. inoculata Stach are redescribed basing on new material, for the latter species the Stach’s individuals were also examined. A key to species of the group is given.
