Dysphania malayanus

This is a paler, duller blue species than the next two, with a more broken, less regularly trapezoid antemedial marking to the forewing. The postmedials are more broken, and the marginal spots more elongate, separated by ground colour along the veins.

Taxonomic note. D. azurea Bastelberger, described from Borneo, appears (colour slide of type examined) to be a synonym of malayanus.

Geographical range. Peninsular Malaysia, Sumatra, Borneo, Palawan. The syntype of proba Butler is labelled as from Darjiling, but no other Himalayan material has been seen.

Habitat preference. Most recent material was taken at light in various lowland forest types.

Biology. The host-plant is Carallia (Forest Research Institute of Malaysia records). In Borneo the Carallia species is C. brachiata (Dr Chey Vun Khen pers. comm.)

The adult moth flies at night.
