Diagnosis.
The forewing above is a richer, more chestnut red than in the previous species,
with a stronger submarginal row of black dots. The subapical markings on the
underside are weaker than in the other species. The apex of the valve of the
male genitalia is distinctly falcate, and there is a rod-like process associated
with the juxta. The aedeagus is very long and has a serrate zone towards the
apex that includes a more prominent spine. In the female genitalia, the ostium
and an extensive basal zone of the ductus are deeply but narrowly cleft. The
bursa has more substantial, broader scobinate bands than in the previous
species.
Geographical
range. Borneo, Singapore, Peninsular Malaysia.
Habitat
preference. A single male has been taken in recent surveys at 1618m on
Bukit Retak in Brunei, but the original material was collected by A.R. Wallace,
probably from the lowlands.
Biology.
Robinson et
al.
(2001) recorded Coffea (Rubiaceae), Heritiera and
Sterculia
(Sterculiaceae)
as host plants for contraria and an unidentified species, but, given the
complexity of the taxonomy, these should probably be treated as generic records
rather than specific ones.
