Tribe Oligaphorurini View in CoL

Oligaphorura absoloni (Börner, 1901) View in CoL . A widespread Holarctic species common in forests, including North Caucasian ones [ Dobrolyubova, 1988; Kuznetsova et al., 2019]. Therefore, it appeared with the forests overgrowing the Tsey foreland. In addition to the pine forests, it also lives in a maple and a beech forest of the nature reserve.

O. montivaga Shveenkova et Babenko, 2022 View in CoL . A recently described species from the marcuzzii -group. In the fauna of the republic, it was found near the village of Nar and referred to as O. sp.n.1 aff. kremenitsai Shvejonkova et Potapov, 2012 [ Kuznetsova et al., 2019].

Oligaphorura sp. 1 . Probably a new species, characterized by the presence of 9 distal setae on the tibiotarsus and the absence of pso on the subcoxae [Yu.B. Shveenkova, personal communication]. In the nature reserve (Tsey), only two specimens were captured, both in a green-moss-grasslessazalea pine forest, 1676 m a.s.l., referred to as O. cf. caucasica (Weiner et Kaprus, 2014) View in CoL [ Kuznetsova et al., 2019].

Oligaphorura sp. 2 . The species was recorded from a pine forest in the vicinity of Verkhniy Tsey, referred to as O. cf. pieninensis (Weiner, 1988) [ Kuznetsova et al., 2019]. Most likely, this is another undescribed species distinguished from O. absoloni by the presence of 5 protective papillae in the antennal organ, and from O. pieninensis (Weiner, 1988) by the absence of pso on the fourth abdominal sternite [Yu.B. Shveenkova, personal communication].

Oligaphorura sp. 3 . A few juveniles of this likely undescribed species were known from the Tsey Valley [see Shveenkova and Babenko, 2022]. In the paper of Kuznetsova et al. [2019], this species was referred to as O. sp.n.2 aff. kremenitsai Shveenkova et Potapov, 2012.

** Oligaphorura sp. 4 . Still another possibly new species of the genus, which is characterized by 2 pso on thorax I and an increased number of pso on the abdomen. In our material, we have only three specimens ( 2 females and one juvenile) from the Tsey Gorge, which have been found in two plots: a young birch forest at an altitude of 2240 m a.s.l. and a mixed forest at 2190 m a.s.l.
