Diagnosis. The male has a pale yellow ground, with the border distal to the
postmedial of both wings mottled broadly with rich brown not seen in other pale
yellow congeners. The postmedials are not markedly punctate. Below, the
fasciation is medium brown, with a large, quadrate pale zone at the forewing
apex. In the male genitalia the flange of the ventral arm is narrow as in subrasata
but often bears a spur. The juxta is diagnostically scobinate on each side.
Geographical range. Japan; N. India, Nepal, Taiwan (ssp. fasciosa); Borneo,
Sumatra, Java (ssp. fulvifascia Warren); Sulawesi (ssp. noda Prout).
Habitat preference. This is a montane species, somewhat more frequent in
the lower montane zone.
