Mucro with two basal, 0 intermediate (rarely one) and two distal teeth (formula 202 or 212) (Fig. 21). Variability. All constant and variable characters are given in Tables 1–2. Discussion. The following 6 species of Plutomurus have been reported from Europe (Barjadze et al. 2020b): P. baschkiricus (Skorikow, 1900), P. carpaticus Rusek & Weiner, 1978, P. jeleznovodski Kniss & Thibaud, 1999, P. kelasuricus Martynova, 1969, P. sorosi Kniss & Thibaud, 1999 and P. unidentatus (Börner, 1901). The new species is similar to P. baschkiricus (Skorikow, 1900), P. carpaticus Rusek & Weiner, 1978 and P. unidentatus (Börner, 1901) by the combination of the following characters: 1) number of prelabral chaetae (2+2); 2) shape of tenent hair (capitate); 3) formula of tibiotarsal spine-like chaetae (002) and 4) number of eyes (6) (Jordana et al. 2012; Barjadze et al. 2020b). The new species differs from P. baschkiricus by having well differentiated spines on dens, while P. baschkiricus has only narrow spines (Skorikow, 1900; Martynova 1969). The new species clearly differs from P. unidentatus by the number of Mc on the abdominal dorsum: 1) Abd. I with three Mc in the new species, while P. unidentatus has two on Abd. I and 2) Abd. IV with three Mc in the new species, while P. unidentatus has five on Abd. IV (Barjadze et al. 2020b). The new species is most similar to P. carpaticus, differing in the 1) number of postocular head Mc: two Mc in the new species, one in P. carpaticus and 2) number of Mc on Abd. II: three Mc in the new species, two in P. carpaticus (Barjadze et al. 2020b). Besides, based on mitochondrial COI gene, the pairwise genetic distance between P. carpaticus from Pieniny and P. ruseki sp. nov. is much greater than intraspecific distance in P. ruseki from two distant localities (Marcin et.al. unpublished data), thus confirming the new species status. P. ruseki sp. nov. also differs from P. carpaticus in habitat preference and geographic distribution. The new species prefers entrance and twilight zone of the caves (troglophilic species), while P. carpaticus is a surface form, found only in forest soil and mosses (Rusek & Weiner 1978 and our unpublished data), thus it may be considered as a trogloxene species. Moreover, P. carpaticus is geographically restricted to the surface habitats of Slovakian and Polish parts of the Pieniny Mountains, while the new species is known from subterranean habitats of several karst regions of Slovakia, and Western Carpathians. It is worth to mention that another possibly undescribed Plutomurus species was found on scree slope in the entrance zone of Silická ľadnica Ice Cave, which co-occurs with P. ruseki. It has head dorsum macrochaetotaxy as in P. ruseki and thoracic and abdominal dorsum macrochaetotaxy as in P. carpaticus. But further evaluation of this taxon will have to await the examination of individuals. Etymology. The species is named in the honour of the late prof. Dr. Josef Rusek (Biology Centre, v.v.i., Institute of Soil Biology, České Budějovice, Czech Republic), an outstanding Collembola taxonomist and ecologist, and Ph.D. supervisor and a great colleague of the last author. Ecology. It is a troglophilous species, considering the presence of pigmented body and 6+6 eyes. It lives mostly in entrance and twilight zone of caves, in several cases it was found to occupy even dark cave zone. It was also found to occupy forest soils and mosses. Distribution. This species is distributed in different karst regions of the Western Carpathians, Slovakia, with exception of the Pieniny Mountains. A Plutomurus specimen with 3 Mc on the Abd. I and II sampled in Perlynna Cave (Eastern Carpathians, Ugolka Karst Massif) in Ukraine, probably belong to this species (Robert Vargovitsh, personal communication).
