KSENIA A. SEMENCHENKO. Two new water mites species (Acariformes: Hydrachnidia) from interstitial waters of the Russian Far East / ZOOTAXA. - N 2429. P. 52-60.
Abstract
Illustrated descriptions of two water mite species, Amerothyasella tiunovae sp. n. and Uchidastygacarus primoryensis sp. n., from interstitial waters of the Russian Far East are presented.
At present hyporheic water mites of the Russian Far East are still poorly known and ch aracterized by fragmentary data. They are represented by four species of the genus Wandesia (Tuzovskij 1982, 1987a, 1988, 1990) and one species of the genus Stygomomonia (Semenchenko 2008). Two taxa of the genus Feltria (F.aculeata Tuzovskij & Semenchenko, 2009 and F. cornuta rossica Tuzovskij & Semenchenko, 2009), found in superficial waters, are presumably also interstitial, as are the remaining representatives of the species-groups (denticulata and cornuta-group respectively), to which they belong. Descriptions of two new species from interstitial waters of the Russian Far East are given in this paper.
The genus Amerothyasella contains two species and was previously known only from North America (Smith & Cook 1999). The genus Uchidastygacarus contains eleven species (five were described from the Japanese Archipelago and six from North America) (Viets 1987; Smith 1992). Both genera are reported from Russia for the first time.
