Malatrogia Hampson
Type
species: castanitis Hampson.
The
facies and wing shape of this monobasic genus are distinctive as described below
and illustrated. The male antennae are strongly fasciculate, the labial palps
typically catocaline.
In the
male abdomen, the eighth tergite has short, broad apodemes, and both sclerites
have slightly more intense sclerotisation in sublateral bands. In the genitalia
the uncus is elongate, hexagonal, but possibly only a modification of an
inverted ‘V’. The valves are simple, rather paddle-like, lacking processes.
The aedeagus vesica has three diverticula, all of which have heavier spining
apically in diverse forms, but no cornuti.
No
females were located for study.
The
monobasic New Guinea genus Crenularia Bethune-Baker (type species concolor
Bethune-Baker)
has similar wing shape (but more uniform grey facies) and male abdomen to Malatrogia
and
probably bears a sister-relationship to it.
