12mm, 11mm. This is the smallest of the three species. The wings are slightly paler than in the other two species, such that the fasciation is clearer; the forewing postmedial is more oblique and sinuous. The male genitalia have the uncus narrower and relatively longer. The valves are more deeply cleft, straighter. The saccus is similar to that of amphusalis. The aedeagus vesica has only one region with coarse spining.
