Euproctis chalcostoma Collenette; Holloway, 1976: 46.
Diagnosis
The four species in this genus divide into pairs: those without as distinct from those with a subapical black spot on the forewing. The first two species comprise the first pair, lacking the spot: they also show much less sexual dimorphism in the darkness of the shading of the wings. The dark area of the wings of chalcostoma are pale grey, whereas they are dark grey-brown in hemibathoides Strand. Genitalia features of all four species are very similar.
Geographical range
Peninsular Malaysia, Sumatra, Borneo.
Habitat preference
The species is uncommon, but has been taken over a range of altitudes from the lowlands up to 1930m, mostly in forested localities.
