Diagnosis.
This is a variable species in the extent to which the fasciae and medial area
are irrorated and blocked in with white. One specimen is similar to a variant of
cyllaria
in
having a brown and fawn variegated border along the dorsum and distal margin of
the forewing, with the rest uniform dark brown. Constant features include the
much more angular nature of the forewing postmedial and the very reduced white
spotting of the hindwing. The forewing submarginal is more irregular over its
anterior half and distinctly concave distad over the posterior part.
Taxonomic
note. Examination of type material (UM Oxford) revealed that the
concept of pulchrivena
in
most literature is erroneous (see above) and that hollowayi and
pulchrivena
are
conspecific.
Geographical
range. Sumatra, Borneo.
Habitat
preference. Eight specimens have been taken in a variety of mostly forested
habitats from the coast to 300m in Brunei, one from 1618m on Bukit Retak and one
from 1790m on G. Mulu.
