Diagnosis. The pale yellow hindwings combined with grey forewings in the male are
diagnostic. The hair pencil on the dorsum of the hindwing is weak. The female
forewing resembles that of the male, but the hindwing is dark grey with paler
areas and a rather sinuous postmedial. The forewing postmedial is similarly
sinuous in both sexes with a slight black fleck within the distal bulge at one
third from the dorsum.
Geographical range. Indo-Australian tropics from Sri Lanka to New Guinea.
Habitat preference. Most material has been taken in a wide range of
lowland forest types, where the species is often frequent. Two specimens were
taken at 1000m on G. Mulu and one at 1200m on G. Kinabalu (Bundu Tuhan).
