A new water mite species in the genus Feltria (Acari: Hydrachnidia: Feltriidae) from Hokkaido, Japan

Abstract

A new water mite species from Japan, Feltria (Feltriella) itoae sp. nov., is described. One male of this species was collected from a river weir in Hokkaido. Although F. (F.) itoae is similar to the male of Feltria (Feltriella) menzeli Walter, 1922, the new species can be distinguished from F. (F.) menzeli by the longer and broader dorsal plates on both sides of the anteromedial plate, and the posterior plate reaching the end of the dorsum.
