16mm. The only specimen is rather brown, but has the buff labial palps strongly recurved over the head, with the third segment, straight and slightly tufted, reaching the centre of the thorax. The centre of the hindwing margin is distinctly produced, and there is a paler creamy-buff, slightly irregular, transverse postmedial evident, and a conspicuous pale patch at the position of the reniform. The genitalia are similar to those of rufithorax except the valves lack the basal projection of the costa, and have a shallow triangular flap from the interior of the sacculus. The aedeagus is shorter than in rufithorax. It has a vesica that also extends mostly dorsally, but with a large scobinate lobe distally.
