Pingasa Moore

Type species: ruginaria Guenée.

species have a characteristic facies of regular, crenulate dark postmedials separating a marginal zone of the wing that is shaded or clouded darker than the basal zone. Within this marginal zone there is a pale, but similarly dentate or crenulate submarginal fascia. A particular generic feature is the presence of two transverse brushes of scales on the hindwing. These are in a different position from the situation in Hypodoxa and Sundadoxa, one being on the discal spot and the other displaced about 2-3mm distally from this in a subdorsal position. In Sundadoxa the whole brush of scales is just basal to the discal mark.

The male antennae are narrowly bipectinate.

Features of the male abdomen include a strong pair of setal patches on the third sternite, an uncal structure shared with the next three genera where the socii have become more or less fused basally, being narrowly separate only over the distal portion, and deep, rather short valves that are often produced at the apices of both the costa and the ventral margin. There are strong coremata. The gnathus is often apically bifid. The aedeagus vesica has a distal sclerotisation or blunt cornutus.

In the female (ruginaria) the ovipositor lobes are of the modified geometrine form: the bursa is large, immaculate, set on a short ductus.

The larvae are robust, with skin granules, polyphagous, sometimes feeding on the reproductive parts of the host-plant.

The genus is widespread and diverse throughout the Old World tropics. There are nine species in Borneo.
