Diagnosis

This and the next species have similar facies, particularly the rather linear forewing postmedial with a subcostal angle and zig-zag.

Taxonomic Notes

The Himalayan H. ratotaria Swinhoe stat. rev. was listed as a synonym of transcissaby Sato (1990 b, 1991). Dissection of the type material indicates the taxon to be distinct.

Geographical Range

Indian subregion to Sundaland.

Habitat Preference

This is one of the rarest Bornean species, the few records being all from lowland forests that have experienced some degree of human disturbance.

Biology

There is a record of this species having Aleurites (Euphorbiaceae) as a host plant in Peninsular Malaysia (Corbett, 1929, Malayan agric. J., 8: 266).
