Heringarosa Gen. n.
Type species: trifurca sp. n.
This genus also has Narosa venation and filiform male antennae.
The ground colour of the wings is dull yellow and the forewings have an
irregular broad ring in the distal half. The diagnostic features are in the male
genitalia; females are unknown.
The eighth tergite is produced into a slender finger that is itself
about one and a half times the length of the average abdominal segment (see also
Flavinarosa). The vinculum, in the region of the saccus, gives rise to a
pair of slender sclerotised processes. The transtillae fuse into a complex
setose structure from which arises a pair of folded membraneous processes
directed back into the interior of the abdomen. The aedeagus is relatively
short, with a substantial spine at the apex.
The genus contains two species, both found in Borneo.
