There is some sexual dimorphism, with the male having a more triangular forewing
with the distal margin straighter, more oblique. In the female the extent of the
bluish grey suffusion in the fasciation is more extensive. The ground colour is
black, the fasciation distinct though slightly diffuse. The hindwing has a
sequence of bands of black and grey, curved in the female but with a straighter
component in the male. In the forewing the fasciae are more oblique, the
postmedial angled subcostally; in both sexes there is a basal area and an
obliquely ovate discal spot that stand out blacker.

There is an undescribed species with similar facies but different male genitalia

preference. Both holotypes are from Sarawak without precise data.
Subsequent material is from Lio Matu (Lio Matoh on the S. Baram at 222m; G.S.
Robinson, unpublished) in the area of G. Murud and from Bidi in the lowlands of
Sarawak, and from the region of Pontianak in lowland Kalimantan. Two males have
been recorded in recent surveys of Brunei: in swamp forest at 15m in Daerah
Belait; in dipterocarp forest at 30-60m in the Labi area. Three specimens were
recorded in the canopy of lowland forest at 170m near the Danum Valley Field
Centre by S.J. Willott (unpublished data).
