10-12mm, 12-13mm. This species is similar in facies to its congener but
lacks the fine white line to the forewing. The dark medial bar to the forewing
is more conspicuous, particularly in the female. The black submarginal band over
the anterior half of the hindwing is set further from the margin, and that on
the forewing incorporates a white spot. There are major genitalic differences,
as indicated in the generic description. The costal ornamentation has a long,
weakly sclerotised, straight digitate process and a shorter, strongly
sclerotised, rather crooked, apically spined process directed towards the rather
slender, long, tongue-like apical part of the valve. The saccular process is
long, slender, evenly curved. In the female genitalia the membrane between
segments 7 and 8 is thickened, rather corrugate. The ductus is short, the neck
of the bursa twice as wide, squarish, sclerotised, and the distal part ovate
with a long, tranverse, gently arcuate, flange-like signum, similar to that seen
in the Myrioblephara group.
