15-16mm. This species is slightly smaller than undulata but has similar facies, except the forewing postmedial and submarginal fasciae are more clearly delineated and less ragged in course. These fasciae on the hindwing are closer together. These features are also apparent on the underside, where the ground colour, particularly of the hindwing, is paler, giving a more contrasted effect. The genitalia have the valves slender, slightly upcurved, tapering, particularly at the apex distal to slight angles on the costal and ventral margins. The aedeagus vesica is typical of the genus, with scobination, but has a number of much more robust short spines near its junction with the aedeagus shaft.
