17-18mm, 17mm. This is the largest of this interrelated group of Bornean species. The fasciation and markings are as in ochrescens, but the dull brown colour is darker from the submarginal outwards in the holotype male, similar but with the basal third also darker in the female, but uniformly paler in the other (Kinabalu) male. The forewing discal mark is much more oblique than in the previous two species. The male antennae are noded, and the subcostal flap of the forewing is as in ochrescens. The male genitalia are similar to those of grisescens but the saccular process only extends to about the mid-point of the valve. The aedeagus vesica is more triangular, with patches of moderately coarse scobination on each of two lobes, surrounded by fields that are finer. The female genitalia have the corpus bursae more spherical, uniformly finely scobinate and with the spine-like signum near its apex.
Holotype. SARAWAK: Gunong Mulu Nat. Park, R.G.S. Exped. 1977-8 (J.D. Holloway et al.), Site 4, 1790m. 452463, BM noctuid slide 19632.
Taxonomic note. Two smaller (14, 15mm), rather worn specimens with much more uniform, much less heavily marked wings but similar male genitalia (slide 19634) from 500m in hill dipterocarp forest on the slopes of G. Mulu may be conspecific or may represent a further species.
Geographical range. Borneo.
Habitat preference. All three specimens in the type series are from upper montane forest, and the two dubious ones are from hill dipterocarp forest.
