Diagnosis. The white ground colour of the wings distinguishes the species from
Bornean congeners. The fasciation, particularly that of the hindwing, is
variably tinged yellow, but never to the complete exclusion of the white ground.
Taxonomic notes. The extent of yellow fasciation is very variable, as is the strength of
spining in the aedeagus vesica and the length of the uncus. A species complex
may therefore be involved, but no clear separation of taxa could be determined.
Geographical range. N.E. Himalaya and Tibet to Hong Kong, Sundaland,
Wallacea, New Guinea and the Bismarcks.
Habitat preference. Most specimens have been taken in lowland forest but
the species has been recorded more infrequently to as high as the upper montane
zone at around 1600m.
