Diagnosis.
Both this and the next species are large, robust, with elongated scale-like
processes at the node of the male antennae. Males of the next species are paler,
browner, with pale brown zones at the forewing apex and obliquely distal to the
antemedial. On the hindwing underside scriptiplena has a discal lunule,
lacking in wallacei, and the postmedial is more distal and strongly
curved over the anterior half; the ground is very much paler in scriptiplena.
Females of the two are more similar on the upperside, resembling males of wallacei,
but can be distinguished by the presence or absence of a hindwing underside
discal lunule and on the shape of the hindwing postmedial.
Taxonomic
notes. The holotype female of wallacei has a hindwing underside
consistent with that of pryeri, therefore the two taxa are considered
synonymous, rather than wallacei being placed as a synonym of scriptiplena
Walker (also based on a female).
Geographical range. Borneo, Peninsular Malaysia; there are single females
from Kei and Dampier I.
Habitat preference. The species has mainly been taken in the lowlands,
but there is one specimen from 1670m on Bukit Pagon, Brunei.
