The paper is devoted to a taxonomic review of Oligaphorurini from the north-eastern part of Palaearctic. Two new species, i.e. Oligaphoruraambigua sp. n. and Oligaphoruraduocellata sp. n., are described. Four species, Oligaphoruranataliae (Fjellberg, 1987), Oligaphorurainterrupta (Fjellberg, 1987), Oligaphorurapingicola (Fjellberg, 1987), and Micraphoruraalnus (Fjellberg, 1987), are redescribed...

A new species, Protaphorura genheensis sp. nov., and two new records, Protaphorura taimyrica (Martynova, 1976) and Protaphorura kaszabi (Dunger, 1978) are reported from northeast China. New localities for P. bicampata are presented. P. genheensis sp. nov. belongs to the 'oligopseudocellar' group as having fewer pso on Th. II-III and can be distinguished by the dorsal pso formula, number of pso ...

Species of Hypogastruridae and Onychiuridae described by D. L. Wray were reexamined and redescribed where necessary from type material and other specimens. Mitchellania hermosa is redescribed and transferred to Ceratophysella. Hypogastrura ireneae is redescribed and H. gravesi is validated with additional material. Hypogastrura gami is synonymized with H. humi and H. utahensis is synonymized wi...

In this paper, the Palearctic genus Dimorphaphorura Bagnall, 1949 (Collembola: Onychiuridae), is revised. The diagnosis of the genus is defined within the tribe Oligaphorurini based on the development of the furcal area, shape of furcal rudiment, and furcal chaetotaxy. Six new species are described: D. olenae sp n. from Ukraine, D. inya sp n., D. pseudoinya sp n., D. sibirica sp n., D. caucasic...

Protaphorura Absolon, 1901 is characterized by the postantennal organ with numerous simple vesicles, the number of chaetae in the distal row of tibiotarsi as 11, the absence of chaeta d0 on the head, the furca reduced to a cuticular pocket with 2+2 dental chaetae, the presence of three or four manubrial rows of chaetae and having anal spines set on distinct papillae (Weiner 1996, Pomorski 1998)...
