Diagnosis. There is some sexual dimorphism in heteroides, the females having
more irregular, less clearly defined fasciae and wings that are more produced in
the centre of the margin. The forewing has oblique postmedial and antemedial
fasciae amid a general brown stippling on white. The hindwing has a lens-shaped
area at the margin divided off by an arcuate brown line. The venation of the
forewing has R1+R2 stalked independently from R3-R5. The harpe of the valve is
rather weak, flattened, and in a more dorsal position.
Geographical range. Peninsular Malaysia, Sumatra, Borneo.
Habitat preference. The species is uncommon, mostly recorded from lowland
forest, but with two records from altitude in Brunei: 1465m on Bukit Retak;
1680m on Bukit Pagon.
