The postmedials are much less oblique than in other members of the genus, that
of the hindwing being obscure. The fasciae basal to the forewing postmedial are
finely zig-zagged, and the submarginal markings lack the stepping typical of the
note. The species is atypical of Ugia in
facies as just described, but also the male antennae are fasciculate. The male
eighth sternite bears a massive corema that has a pair of small lateral lobes
basally. The male genitalia have a strong paratergal sclerite. The valves lack a
costal process and have a prominent corema. The female genitalia have the ostium
between the seventh and eighth segments and associated with the latter by a
simple postvaginal plate. The ductus is narrower than the ostium, unsclerotised,
just longer than the seventh segment. The neck of the corpus bursae is set
asymmetrically on it and is long, corrugated, scobinate, protruding basally
beyond the junction with the ductus as a slight appendix that leads to the
ductus seminalis. Distally there is an ovate portion, more lightly scobinate,
with a signum at its apex consisting of a small spine on a broader base. The
species resembles Avittonia Hampson (p. 398) in many of these abdominal features.

but a few specimens were taken at 1000m on G. Mulu and singletons at 1500m and
1930m on G. Kinabalu.
