15-17mm, 15mm. The facies is similar to that of ochrescens except the ground colour is medium greyish brown, with more irregular shading of darker brown over the marginal zone. The forewing discal mark is larger, somewhat ringed, with a dark but diffuse medial band between it and the dorsum. The dentate postmedial of the forewing is more obscure and more sigmoid than in ochrescens. The medial fascia of the hindwing is distal to the discal mark rather than basal to it. The male antennae are noded. The male genitalia have the valves expanding slightly to the rounded apex. The saccular process tapers to about two thirds from the valve apex. The aedeagus vesica has a field of moderate teeth over its distal half and finer scobination elsewhere. The female has a corpus bursae smaller than in ochrescens and the next species; the area around the origin of the ductus seminalis is convolute as in the former, but the signum is nearer the apex as in the latter.
