Diagnosis. This is the largest Bornean species, the reddish brown of the
forewings relatively pale. The yellow zone is constrained by a gently curved
border, concave distad, running from the centre of the dorsum to the distal
margin just short of the apex; it is crossed by reddish brown squiggles, with a
more dense band subbasally. The hindwings are white with a broad, pale red-brown
border. The male has a central swelling to the forewing costa, marked by a tuft
of hair on the upperside.
Geographical range. Himalaya, S.E. Asia, China, Japan, Peninsular Malaysia,
Habitat preference. Three specimens have been taken in recent surveys, all
from montane forest; 1500m on the limestone G. Api, Sarawak; 1465m on Bukit
Retak, Brunei; 1760m on G. Kinabalu. These are probably all in the upper montane
