The
facies and forewing shape of the two included species is described below. They
are delicately built moths. The phragma lobes on the second abdominal tergite
are reduced, shallow.
The male
abdomen of the type species has a typical framed corematous eighth segment. The
posterior margin of the tergite has small apodemes at the distal end of each
lateral arm of the trifid structure. In the genitalia, the uncus is short,
hooked. The tegumen is much shorter than the vinculum, but there may also be a
long, narrow, paratergal sclerite in the type species. There is a broad saccus.
The valves are deep basally, tongue-like, slightly upcurved, with, just ventral
to the centre of the base, a slight lacuna leading to a sparsely setose,
tongue-like plate directed distally over the interior surface of the valve. The
aedeagus is long and slender.
In the
female genitalia the ostium is at the junction of segments 7 and 8. The ductus
is long and narrow, sclerotised over the less tapered distal half of this
section up to a colliculum just basal to the junction of the ductus seminalis
with the fluted neck of the bursa. The corpus bursae is spherical, with
scobination that becomes larger and coarser with progress distad from an
immaculate basal fifth.
