Abstract
Three new species, Hypogastrura variatasp. nov., Xenylla aculeatasp. nov., and X. arneisp. nov., are described based on material from coastal communities of the Sea of Okhotsk, northeast Russia. Taxonomic remarks concerning a little-known species, H. yosii Stach, 1964, found in coastal wrack sediments on Kunashir Island, Kuriles are also given. COI sequences of the above species are analysed, thus allowing for their species statuses to be confirmed.
Highlights
The first information concerning the collembolan faunas of the Far Eastern regions of Russia was obtained during the expedition of N.A.E
The material collected by that expedition on the northern coast of Chukotka was published by Schött (1893), who recorded slightly fewer than 20 species of Collembola from the region
This paper is devoted to descriptions of three new species of the family Hypogastruridae from the coastal communities in the northern part of the Sea of Okhotsk
Summary
The first information concerning the collembolan faunas of the Far Eastern regions of Russia was obtained during the expedition of N.A.E. One of the most characteristic features of the new species is its highlevel variability of such important morphological traits as the number of PAO lobes and dental setae, as well as the shape and presence of a mucro (Table 2).
