Ercheia kebea


Diagnosis. The general appearance is typical of the genus, but the forewings are easily distinguished by the strong central projection to the dorsal margin between the antemedial and postmedial. The forewings in the female are usually a uniform grey brown but can be slightly more variegated with a longitudinal black streak or extensively pale grey except for the basal area and the subapical semicircle on the costa. In the much rarer males the forewing area distal to the antemedial is often a distinctly paler grey except for the subapical costal mark and a few smaller patches. The hindwings in both sexes have a central pale band rather than dots.

Taxonomic note. Poole (1989) treated albirenata Gaede as a good species, but Gaede, in his treatment of the genus in Gross-Schmett. Erde 11, placed it as a synonym of kebea, a decision confirmed by examination of the holotype (in MNHU, Berlin).

Geographical range. Thailand (VK), Sumatra, Borneo, Seram, New Guinea, Queensland, east to Fiji.

Habitat preference. The only Bornean specimen taken in recent surveys is from lowland forest at 60m in the Ulu Belait of Brunei. The original material of borneensis was from Bidi in the lowlands of Sarawak, there is a specimen from Beaufort in Sabah, and the holotype of albirenata is a male collected in the Kinabalu area by Waterstradt.
