Genus Nipponaetes Uchida, 1933

Nipponaetes Uchida, 1933b: 160 . Type: Hemiteles (Nipponaetes) haeussleri Uchida, 1933 . Original designation.

Potia Seyrig, 1952: 36 . Type: Potia inelegans Seyrig, 1952 . Original designation.

Thalops Townes, 1958: 57 . Type: Thalops fessus Townes, 1958 . Original designation.

Two species, N. haeussleri (Uchida, 1933) and N. striatus Momoi, 1970 , have been recorded from Japan. In this study, I re-describe the former with new distributional data below. Momoi (1970) used the striation of T II for the separation of both species, while this character states varied ( Konishi et al., 2014; in this study). Thus, taxonomic position of N. striatus should be revised in the future study. Japanese species can be distinguished by the following key.
