Diagnosis. This is a small species with a
characteristic facies of rich brown markings and shading on pale ochreous
cream. The forewing has an angle at the centre of the distal margin, and the
apex is very slightly falcate; the orbicular is prominently paler. The hindwing
is less shaded by brown, and the fine fasciae are more prominent. Males have an
elongate, elliptical, dark brown patch of androconial scales in a clear zone at
the anterior of the hindwing.
Taxonomic note. The relationship of this species
to typical Nagadeba is discussed in the generic account.
Geographical range. Borneo, Sumatra (HS /
Habitat preference. The original material was taken
in Sarawak by A.R. Wallace. Five specimens
have been collected in recent surveys, one from secondary and coastal
vegetation at Seria and two from lowland forest at 300m in the Ulu Temburong,
Brunei, one from 100m on G. Santubong near
Kuching in Sarawak, and one from an area of
disturbed forest at 550m in the vicinity of Poring near G. Kinabalu. In
addition, eight out of ten specimens (three retained) recorded in a survey of
forests near the Danum Valley Field Centre (S.J. Willott, unpublished data)
were from logged rather than primary forest.
