Diagnosis. This species is best distinguished by the brown shading between the
hindwing antemedial and the discal mark. There is brown suffusion elsewhere
particularly in association with the fasciae; the fasciae are rather weakly
defined on the forewing. In the male genitalia the valves have three spur-like
processes: central, basal; distal, saccular; subcostal, central.
Taxonomic note. Sumatran material has the male genitalia distinct: the saccular process
is more distal, longer: the uncus is more robust, the apical portion shorter,
blunter; the aedeagus has a massive lateral spine. In the female the sterigma is
more complex, more heavily sclerotised. The differences are such as to indicate
specific status. Peninsular Malaysian material may be more referable to that
Geographical range. Borneo.
Habitat preference. The majority of specimens taken in recent surveys
were from lowland rainforest, the highest being a male from 1000m in the lower
montane forest zone of G. Mulu and a female from 1200m on G. Kinabalu.
