See the generic description. The pale edging to the dentate fasciae is diagnostic.

Taxonomic notes. This species differs from the type species in having more dentate fasciae, a more definite spur to the ventral angle of the valve, and a somewhat shorter, more bulbous cornutus in the aedeagus vesica, though this last is longer, narrower in Sundanian material.

Geographical range. N.E. Himalaya, Taiwan, Burma, Peninsular Malaysia, Sumatra, Borneo.

Habitat preference. The majority of Bornean specimens is from upper montane forest on G. Kinabalu, Bukit Retak in Brunei, G. Mulu and G. Api in Sarawak. On G. Mulu one specimen was taken in lower montane forest at 1000m.
