However, several Rhyacodrilus species are distributed in Lake Biwa, and the possibility that specimens examined by Semernoy correspond to some species different from R. hiemalis cannot be excluded. According to Ohtaka (1995), R. hiemalis differs from R. sokolskajae by large morphological differences and should be regarded as a separate taxon.
