11-12mm. The facies is generally as in larusalis, though the species is smaller. The forewing submarginal and, to a lesser extent, that of the hindwing, are much more strongly zig-zagged, that of the forewing meeting the postmedial. The hindwing postmedial is a straight, pale line as in larusalis. The male genitalia have valves typical of the genus, with the costal spur subapical as in muluensis, but more strongly angled away from the margin. The aedeagus vesica has a more extensive area of coarse spining and also more fine scobination.
