9-10mm. This species is
slightly larger than the previous three, with paler, more excavate hindwings.
The distal bands on the forewing are broader, the more basal ones triangular
rather than semicircular and reaching the costa; the two are separated by a
broader white area. The male genitalia have the distal parts of the saccular
process much broader than in the previous three species and diagnostically
apically bifid. The aedeagus apex is ringed with small spines and several larger
ones, but the vesica is only finely scobinate over its distal half.
