12-13mm. This species resembles proximalis (10-11mm) in forewing facies but is larger, with a straighter oblique margin to the pale basal zone. It
is also variable, two of the more strikingly marked forms being illustrated in
the Plate, and a more uniform one by Holloway (1976). The male genitalia
resemble those of ferrimissalis Walker in the equality and parallel
arrangement of the valves, but the harpe is larger, more expanded apically, and
the uncus is deeper. In the female genitalia the lamella postvaginalis is
distinctively finely scobinate, and the bursa is elongate, slightly curved,
tapering smoothly towards the base; there is no signum but the scobination is
coarsened slightly centrally.
