Taxonomic Notes

Differences in the male eighth sternite of the three races were noted by Tams (1953). In addition, the valve of bidiensis has the dorsal lobe short, blunt,rather than long and finger-like, and the ventral lobe is like an open hand rather than serrate, acute.

The aedeagus terminates in a single spine rather than being deeply bifid.

Leong (2010c) described and illustrated a newly emerged female of Alompra ferruginea in Singapore. It had eclosed from a cocoon within a curled up leaf of a Garcinia (Guttiferae) sapling. The cocoon incorporated larval setae and was covered with a whitish powdery bloom that also extended onto the leaf. The moth repeatedly extruded a bright yellow gland dorsally on the intersegmental membrane between the terminal abdominal segment and the genital segments for a period of over half an hour, possibly some sort of calling behaviour for males. Zolotuhin (2009b) illustrated the first instar larva of ferruginea. it is very similar in appearance to the early instar Trabala larva illustrated by Chung et al. (2008), with each segment having several pale yellow rings close together, separated by a black ring at the junction with neighbouring segments. In Alompra, the number of these rings varies from two to (on the middle abdominal segments) three, compared with four closely packed ones in Trabala. The head in both is dull orange.
