11-13mm. This species is robust for its small size, resembling depressalis to some extent in facies, in that the basal zone and areas immediately distal to the postmedial are blackish, and the postmedial is also biarcuate and slightly oblique. The medial zone is much paler, a creamy fawn, and there is a conspicuous blackish lunule on the basal side of the reniform stigma. The male antennae are strongly fasciculate, and the straw-coloured labial palps extend back to the centre of the thorax. The male genitalia have slender, tapering, upcurved valves. The sacculus terminates at the centre of the ventral margin, projecting as a rounded off acute angle. The aedeagus vesica extends laterally across the apex of the aedeagus to a length greater than the aedeagus itself, and has a scobinate lobe distally at the centre of the longest extent from the apex; associated with the base of this lobe is a slender cornutus.
