The taxonomic status of Dianemobius fascipes (Walker 1869) from Nepal (Kathmandu) and D. nigrofasciatus (Matsumura 1904) from Japan (Akiruno City near Tokyo), Korea (Incheon near Seoul) and Russia (Novosibirsk) is discussed, based on a comparison of acoustic advertisement signals. The sounds of D. nigrofasciatus are described for the first time from the northwesternmost locality of its range in southern Siberia, Russia. According to amplitude-time characteristics, there are no differences between male signals of from Russia, Japan and Korea. However, the signals slightly differ from those of D. fascipes from Nepal. There are no morphological differences between these taxa, with the exception of the color of the hind tibia. Male genitalia are similar and slightly differ in the degree of development of the ectoparamere lobe. Thus we suggest to consider D. fascipes as a polytypic species which includes two subspecies: the nominative, southern D. fascipes fascipes stat. resurr., common in the Oriental Region, and the northern D. fascipes nigrofasciatus stat. resurr., known from the eastern part of the Palearctic Region.
