Diagnosis. This and the next species have similar facies, particularly the rather
linear forewing postmedial with a subcostal angle and zig-zag. H. sommereri is
paler, marked with a richer brown; on the underside the veins are picked out
darker in a zone anterior and distal to the forewing discal spot. In the male
genitalia the valve of sommereri lacks a subcostal band of spines.
Taxonomic notes. The Himalayan H. ratotaria Swinhoe stat. rev. was listed as a
synonym of transcissa by Sato (1990b, 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
