Diagnosis. This subspecies is similiar to the nominate subspecies, but can be distinguished by the following characters: the hindwing medial line is broader, the postmedial line is almost straight. In the male genitalia (Sato, 1980), the tegumen posterior processes are shorter; the left process of the juxta is smaller, about onesixth length of the juxta. In the female genitalia (Sato, 1980), the signum is smaller, with 8–13 spines, which are longer than that of the nominate subspecies.

Distribution. Japan.
