Diagnosis.
The forewing facies is somewhat similar to that of absorbens,
with a pale-edged central patch, but this never reaches the distal margin. The
hindwing is much darker, with an irregular pale band medially and a fainter one
submarginally.
Taxonomic
note. The holotype male of lichenosa Hampson
(Sikkim) has facies and male genitalia as in orbifera.
The features of the male genitalia of D. ferrosticta Yoshimoto (Burma) suggest a close
relationship to orbifera,
which is variable in the development of pale areas on the wings; in ferrosticta
these
are not evident.
Geographical
range. Borneo, Thailand (VK), Sikkim.
Habitat
preference. The holotype was taken by A.R. Wallace in Sarawak. Three
specimens have been taken recently in Brunei, all from lowland forest:
dipterocarp forest at 100m and 300m in the Ulu Temburong; heath forest at 15m at
Telisai.
