Diagnosis. In Borneo this and the next species, impingens Walker, can
be distinguished on size and wing shape: the next species is larger and has the
forewing apex more produced. The subapical, triangular dark mark on the costa is
shallower in the next species. Males tend to be darker and less clearly marked
on the forewing in both species, particularly in the area around the reniform.
In the male genitalia impingens is distinguished by a tuft of setae in
the uncus position and also by a strongly hooked costal process on the valve.
This latter is only slightly curved and has a lateral spur dorsally.
Geographical range. Burma, N. India, Borneo.
Habitat preference. The species is much rarer than the next, with all
material in recent surveys being from lowland and coastal forest in Brunei up to
an altitude of 300m. Older material from the G. Mulu area of Sarawak or
collected by A.R. Wallace in Sarawak is without altitude data.
