Diplurodes kerangatis sp. n.
Diplurodes kerangatis ♂
(paratype) |
 |
♂♀
11-13mm. This species is very similar to D. sugillata but may be
distinguished by the browner tinge to the grey suffusion, a suffusion that
usually obscures the medial zone of the forewing. The postmedial fasciae are
less dentate, more sinuous in course. The male genitalia have a slender,
spatulate uncus and no tongue from the tegumen. The valves are trapezoid with a
single, large, digitate process at the sacculus that lies close to the ventral
margin and is slightly upcurved at the apex.

Habitat preference. Most of the specimens were taken during the Mulu
survey in wet heath forest (kerangas) on raised river terraces in the lowlands.
A few are from hill dipterocarp forest, and there are records also from lower
montane forest on G. Mulu and the limestone G. Api.
