Diagnosis

The ground colour is pale yellowish or pinkish fawn, marked finely in rich brown or reddish brown. Many specimens have a longitudinal subcostal line in this colour. On both wings the postmedial appears double, the interior component more regular than the outer, that of the forewing more or less straight.

Taxonomic Notes

There is great variation in wing colour, presence or absence of the subcostal line and, in the male genitalia, the length, robustness and curvature of the process on the valve sacculus. Facies and genitalic variation appear to be independent, nor could a geographic basis for it be detected in the fifteen specimens dissected. A further study of this complex situation will be undertaken for Heterocera Sumatrana by D. Stüning and M. Sommerer.

Geographical Range

N.E. Himalaya to Taiwan and Sundaland.

Habitat Preference

All Bornean material seen has been from lowland forest.

Biology

The larva has been reared in Hong Kong by M.J. Bascombe (pers. comm.). It is speckled brownish grey with transverse rows of whitish dots in the final instar. These white markings are more extensive and conspicuous in earlier instars (above). The species has been reared from guava (Myrtaceae), Desmos (Annonaceae), Buchanania (Anacardiaceae) and Punica (Punicaceae) (Pholboon, 1965; M.J. Bascombe, pers. comm.; unpublished IIE and Forest Research Institute of Malaysia records).
