Callidrepana pulcherrima

Callidrepana pulcherrima

Males are dark brown, lacking strong fasciation, and are also distinguished by the large, slightly paler, bilobed discal spot on the forewing and more conspicuous, irregular, pale submarginal patches on the hindwing. The female is larger, paler, with emphatic dark brown postmedials: the discal patch of the forewing is similar to that of the male though weaker. The sexual dimorphism is seen also in the falcation of the forewing: weak only in the male but emphatic in the female, with the margin generally more convex than in other species, contrasting with the acute, narrow apical hook. The black submarginal dots of the forewing are much nearer this margin in both sexes compared to other brown congeners.

Taxonomic notes. The sexual dimorphism of this species led to females being described separately as praeusta. The structure of the male genitalia indicates affinity with the next species.

Geographical range. Burma, Peninsular Malaysia, Sumatra, Borneo.

Habitat preference. All records are from lowland dipterocarp forest, but the species is uncommon.
