Diagnosis and taxonomic notes. The holotype is female, a paler grey than kerara, with
a broadly darker submarginal mark parallel to the straighter posterior section
of the margin: it is reduced to a row of black flecks on the veins when parallel
to the anterior section. There is a distinctly paler grey zone at the base of
the hindwing. Males tentatively associated (above) are a similar shade of grey with a more even row of submarginal
dark spots on the forewing. They are distinguished in the genitalia by:
relatively small valves and large saccus (Bornean male); strong processes from
the centre of the costa of more elongate valves, and narrower, shorter saccus
(Peninsular Malaysia male). The gnathus is weak.
Geographical range. Borneo, Peninsular Malaysia.
Habitat preference. The original material was taken in a lowland area of
Kalimantan. The possible Bornean male is from the boundary of wet heath and
alluvial forest on a river terrace west of the Melinau Gorge in Sarawak.
Biology. The species has been reared in Peninsular Malaysia from Calamus manan
(H. Steiner, in litt.)
