Prochasma scissivestis Prout  
Prochasma scissivestis Prout, 1926, Sarawak Mus. J., 3: 205.

Prochasma scissivestis (holotype)

The ground colour is white, speckled and fasciated with dark dull brown, more intensely on the forewing than on the hindwing. On the forewing the submarginal is evident as a fine white zig-zag.

Taxonomic notes. Placement of this species in Prochasma needs confirmation, as unfortunately all male specimens have lost their abdomens. The female genitalia have the ovipositor lobes more setose, less darkly sclerotised. The neck of the bursa is long, narrow, flimsy, without sclerotisation. There is no signum.

Geographical range. Borneo.

Habitat preference. All four specimens seen are from the upper montane zone between 1500m and 2000m. Records are from G. Murud, Sarawak (the type locality), and G. Kinabalu.
