Gadirtha inexacta


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.
