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,
Sumatra, Borneo.
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
zone.
Biology.
Sugi (1987) recorded Quercus (Fagaceae) as the larval host-plant in
Japan.
