18mm. The forewing facies is similar to that of calaina except the basal
black block is more elongate, separated from the dorsum by a narrow pale zone
that broadens and becomes more ochreous towards the base. Distally, the black
block extends to the discal ring (well separated in calaina), which is
itself partially filled with black rather than being open. The submarginal zone
is also more extensively black. The male genitalia have a very weak saccular
process; the costal ornamentation is not thumb-like but is of the centrally
crimped flange type that extends from the base of the subbasal area to a more
central and distal position in the valve. The aedeagus has a central comb of
small spines but no significant spining in the vesica.
