Diagnosis

This species, with the exception of a single aberrant specimen, lacks the typical fasciation of the genus, which led to it being described in Heterostegania Warren. The ground colour is dull pale orange (paler in the female), more or less totally suffused with brown to appear reddish. The paler ground is exposed in apical, discal and antemedial patches in the forewing and in an irregular post-discal zone of the hindwing. The extent of these patches varies but is usually greater in the female.

Geographical Range

Borneo, Sumatra (Heterocera Sumatrana collection).

Habitat Preference

Originally described from G. Kinabalu, this species is also known from G. Mulu in Sarawak and Bukit Retak and Bukit Pagon in Brunei. It is frequent in upper montane forest (1500-2110m).
