11mm. The wing shape is typical of the genus. The colour is rich, dark
reddish brown, with darker fasciae as illustrated. The fasciae consist of a
clearer reddish brown band edged on each side narrowly by dark brown. Flanking
these fasciae and at the wing margins are irregular, rather linear, pale blue
markings, also lined with dark brown. There is a similar, rather zig-zag
submarginal pale blue fascia on both wings. In the male genitalia, the uncus and
divided valves resemble those of biconjuncta and the next species, but
the notch at the apex of the uncus is much narrower, the gnathal arms distinctly
angled subbasally, and the central part of the valve is relatively much larger
and broader.
