Heterostegane subfasciata Warren,
1899, Novit. zool., 6: 43.
Diagnosis. This is a small species with weak, rather straight fasciation on the
upperside, the strongest fascia being the blackish submarginal of the forewing.
The underside has the fasciae very much stronger in dark brown, the first
postmedial being flanked by much broader medials and submarginals on both wings.
The furca of the male genitalia has the arms asymmetric, darker, one much longer
than the other.

tuft of scale setae on male sternite 4 as discussed in the generic description.
Geographical range. Borneo, Singapore, Java, N.E. Himalaya.
Habitat preference. No recent material has been seen. Old Bornean
material is from lowland localities (Baram, Penungah, Pulo Laut).
