, 11-12mm. The male antennae are less broadly bipectinate than in pallidifusca. The wings have a more ochreous ground with the fasciation, particularly the hindwing postmedial, more evenly and finely crenulate, though more broken. The forewing postmedial is more distant from the discal mark where it approaches the costa. The hindwing discal mark is more evident, distinctly linear. The male genitalia are much more robust than in pallidifusca, the valves triangular, slightly sinuous, tapering to a narrow apical spine. The aedeagus vesica is very much larger, with two lobes invested with many short, broad based spines, and with finer scobination elsewhere except in the extreme distal part. The female genitalia have the ductus and corpus bursae very much larger than in pallidifusca, the former narrower, sclerotised, and the latter over three times as long as the ductus, expanding towards the apex, with strong corrugation basally, grading away to the centre, just beyond which is a pair of longitudinally elongate patches of spines. The base of the ductus seminalis is slightly coiled and arises from the base of the corpus bursae.
