Callizygaena unipuncta Swinhoe

Pteroceropsis unipuncta Swinhoe, 1904, Trans. ent. Soc. London, 1904: 154.

Diagnosis

The species is mostly black but much smaller and more delicate than C. ada, and males have striking clublike antennae, distally swollen, scaled and bipectinate over this swollen zone, the pectinations long on one side and setose. All forewing veins arise directly from the cell without branching. The wings are narrow, the forewing somewhat triangular, black with a white discal patch and an iridescent blue patch between it and the dorsum; there is also an iridescent blue band antemedially. The hindwing is an elongate oval, centrally transparent over the basal two thirds.

Geographical range

Habitat preference

Material is restricted to the original series of both sexes from Kuching in Sarawak and Sandakan in Sabah, both coastal towns.
