Diagnosis

This is one of the smaller Bornean species, all of which have a paler, more variegated upperside: the wings below are strongly fasciated with black, the postmedials in the male having components elongated into striae. The submarginals below are more continuous, enclosing the postmedial spots: in the other smaller species the submarginals are more broken. Dissection of male and female genitalia is recommended: the male has a rather ovate, uniformly setose valve, the female a sclerotised patch basal in the bursa additional to the signum which is broad, rather than a narrow band.

Geographical Range

Indo-Australian tropics from the Indian Subregion to Queensland and New Caledonia.

Habitat Preference

Only one Bornean specimen has been located, from near Pontianak in Kalimantan. No altitude data are given.

Biology

Bell (MS) described the biology in S. India. The eggs are laid singly on the leaves, twigs and axils of the host-plant, and the young larvae prefer to feed on young leaves. The larva is cylindrical, narrowing slightly at each end. The head is very slightly and broadly bilobed, wider than T1, and yellow-green in colour. The body is a rosy pinkish green, variable in shade, with a white, longitudinal dorsolateral line and a pale band in the spiracular region. Young larvae sit on the edges of leaves in a variety of postures, older ones being more on the underside and eating holes in the lamina. The pupa is formed in a slight silken cell in a rolled leaf edge. The host-plants recorded were Ardisia and Embelia (Myrsinaceae).
