Nipponasura Inoue, 1965: 241 (as genus).

T y p e s p e c i e s: Nipponasura sanguinea Inoue, 1965 (by original designation).

Diagnosis. The single known member of the subgenus is significantly smaller than both species of the subgenus Sesapa . The male genitalia are similar to those of Sesapa , but differ by the horseshoe-like merged transtillae with long and narrow transtillar processes covered with spinules, absence of medial costal processes and the narrower vesica (in Sesapa the vesica is broad, globular). The female genitalia differ from those of Sesapa by the rugose antevaginal plate, the longer and broader ductus bursae and the more or less globular corpus bursae.
