Diagnosis

The forewings are distinctive, with straight, darkened distal margins and fine, stippled-striate, dark brown markings evenly over the fawn ground of the rest of the wing.

There is a slightly more prominent black discal dot.

Taxonomic Notes

Specimens dissected from Sulawesi and New Guinea had a much shorter costal process, a less sclerotised anellus and a larger single cornutus and denser multiple one in the aedeagus vesica.

Geographical range

Bali, Borneo, Peninsular Malaysia, Sumatra, Philippines, Sulawesi, N. Moluccas, New Guinea.

Habitat preference

Most older material is from the lowlands, e.g. Bidi in Sarawak, but single females taken in recent surveys are from 1930m on G. Kinabalu as well as from lowland forest at the Danum Valley Field Centre.

Chey (1994) recorded two specimens from plantation and secondary forest in the lowlands of Sabah.
