Diagnosis. The wings are blackish brown with a somewhat greenish irroration. There are finely zig-zag postmedials, that of the hindwing angled centrally. The forewing has the discal lunule narrow, white, with darker edging basad, and there is a narrow white submarginal line over the anterior half of the wing. The hindwing may also have a similar discal lunule, but it is less conspicuous than that of the forewing. The male antennae are unipectinate, slightly sinuous centrally.
Geographical range. Borneo, Peninsular Malaysia.
Habitat preference. The original material consists of singletons from around 600m on G. Poi and G. Penrissen in Sarawak. There are also two without altitude data from G. Marapok. Recent surveys have yielded two further specimens, one from wet heath forest at 150m on a river terrace just west of the Melinau Gorge in Sarawak, and the other from the understorey of dipterocarp forest at 170m near the Danum Valley Field Centre in Sabah.
