Female genitalia - Papillae anales slightly sclerotized at anterior margin and truncate from lateral view; 8th sternite absent; apophysis posterioris extending anteriorly to anterior margin of 8th tergite; apophysis anterioris slender, extending anteriorly to medial part of 7th tergite; ductus bursae short, narrow and membranous near antrum, braodened at posterior part; corpus bursae 2.5 times longer than 7th sternite, signum absent, appendix bursa biconical with wrinkled ductus seminalis arising from conjuction of ductus corpus; additional internal sclerites arising from posterior part of ductus bursae and appendix bursae.

Eda (2000) considered that the presence of an oblique submarginal stripe in forewing cell m1 could be a diagnostic character of nobilior. However, our examination of a long series of specimens does not corroborate this idea because of the highly variable size and shape of the stripe in this species.
