Diagnosis. This and the next two species have similar facies of pale fasciation and other marking against a rather greenish dark brown ground. In ablualis the postmedials are more linear and regular, particularly that of the forewing. The forewing costa is also pale, and the reniform is a pale dot rather than a lunule. There is no pale orbicular stigma (present in the next two species). In males the area basal to the postmedials is often generally paler, but females tend to be more uniformly dark, and the fasciation may be obscure.
Taxonomic note. There is some variation in the male genitalia through the range of the species. In Japan (Owada, 1987: fig 225), the dorsal angle of the valve apex is squarer and the costal process more prominent than in a New Caledonian male illustrated by Holloway (1979: fig. 148). In Borneo the valves are closer in shape to those of Japanese material.
Geographical range. Indo-Australian tropics north to Japan and east to Queensland, Vanuatu and New Caledonia.
Habitat preference. This is a species of the lowlands, not recorded above 100m in recent surveys and mostly from extremely disturbed habitats. Older material is mostly from Bidi, a lowland town in Sarawak.
