13mm. The antennae are unusual within the genus, broadly bipectinate, straw-coloured. The labial palps are strongly upcurved. The subcostal flap of scales on the underside of the forewing is reduced to a short ragged zone just distal to the retinaculum. The ground colour is straw, with faint, darker narrow antemedial and postmedial fasciae on the wings on either side of the discal marks. The forewing fasciae are acutely flexed where they are in line with the discal spot. This spot is conspicuous, black, central, and there is a small orbicular dot at one quarter. There is a broad band of dark brown suffusion just distal to the hindwing postmedial, and the rest of the marginal zone and all that on the forewing is suffused a more medium brown. There are small dark brown triangles on the veins along the distal margins of the wings, but the fringes are uniform straw colour. The genitalia are narrower than in ocellatus, but the valves are slightly sinuous, much longer, extending to the apex of the uncus, which is very slightly bulbous. The saccular process is slender, tapering, slightly incurved at the apex, extending to about two-thirds on the valves. The aedeagus vesica is smaller and more globular than in other Bornean species, with no obvious scobination.
