10-11mm. Externally the
species is very similar to pulverea, but is distinguished by an
androconial patch concolorous with the wing and by the male genitalia. The
saccular process of the valve is less strongly hooked, and the saccus is bulbous
rather than triangular. The aedeagus vesica has two, rather than three, spiny
plates, and these are more finely serrate. The third plate in pulverea is
very large, elongate, densely and coarsely spined.
