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.
