Guenee. In Craniophora species the forewing margins
are much less oblique, the hindwings are pale yellowish brown (males) or grey
(females) with a much stronger, somewhat punctate postmedial on the underside.
notes. A. denticulata Moore stat. rev. from the Himalaya is distinct, having a strongly
bifid distal process on the sacculus. The corona of the valve is similar to that
of Trichosea species.
preference. The species is most common in montane localities, from 1200m to
1930m on G. Kinabalu, in lower and upper montane forest on G. Mulu and G. Api in
northern Sarawak and on Bukit Retak in Brunei. A few specimens have been taken
in lowland dipterocarp forest and alluvial forest.
Gardner (1941) described the larva in India, a description probably referable to
denticulata rather than rubiginosa. The body is mostly black
marked with red: the head is dark red; the primary setae are borne on chalazae
and are red. There are no verrucae but segments A1-A3 have paired, dorsal,
rounded, densely pubescent swellings and there are four on A8; otherwise
secondary setae are not apparent.
host-plant noted was Terminalia (Combretaceae).
