Diagnosis.
The postmedials of fore- and hindwings together form a smooth and shallow curve
that runs approximately parallel to the distal margins at two-thirds. Two main
variants occur: with this postmedial curve entirely edged with a white band;
with just a white bar at the forewing costa. There is usually also an irregular
row of white patches submarginally.
Taxonomic
note. The only Bornean male, when dissected, showed slight differences
in genitalia compared with a Himalayan male. It had the ventral angle of the
valve apex flexed out more, and the process just interior from this angle is
acute rather than ampullate. The aedeagus and the diverticula of its vesica are
somewhat narrower.
Geographical
range. Himalaya, Taiwan, Burma, Thailand (VK),
Sumatra, Borneo.
Habitat
preference. Five specimens have been recorded from montane forest during
recent surveys: two from 1618m on Bukit Retak and one from 1670m on Bukit Pagon
in Brunei; two from 1930m on G. Kinabalu.
