Distribution of Chinese
Holotype ♂ –
This species is characterized by the rosy-colored forewing with a longitudinal greyish black stripe at base below costa. It can be distinguished from its congeners by the costa with a triangular distal process arising from 2/3 length of valva, the stout phallus with three thornlike cornuti located at middle in the male genitalia; and the antrum angularly protruding backward posterolaterally in the female genitalia.

This species is characterized by the discocellular spots being fused to a kidney-shaped stigma, in the male genitalia by the costa of valva having a distal process straightly bending backward, forming a right angle with the valva, and in the female genitalia by the corpus bursae having a large elongate spined sclerite extending from the posterior end to middle or to near anterior margin.

This species is conspicuously different from its congeners by the costa of valva weakly sclerotized and lacking the distal process, the juxta with gradually broadened, posteriorly rounded and spinulate lateral lobe, and the vinculum with a small papillate anteromedian process in the male genitalia; and by the antrum deeply and widely concave at middle, elongate featherlike posterolaterally in the female genitalia.
