Clypeus (Fig. 1E) dark brown. Genae (Fig. 1B, D) black. First segment of antennae (Fig. 1A–E) with black brown stripe at apical part, second segment with a black brown stripe oblique from base to center, apical part with dark brown ring-like marking. Forewings (Fig. 1F) light yellowish brown, 2 large transparent spots near basal and middle parts, apex of each apical cells with transparent spot, inner side of crossveins with 3 dark brown burl spots, burl spot with lateral sides small, middle part big, Sc 2, R 1, Rs of apical part with small dark brown spots.

Anal segment (Fig. 2C–E) short, without anal process, wider than long in lateral view, anal style long. Genital styles (Fig. 2F–G) lamellar, broad, basal and near middle parts each with long spiny process, basal one with several small dentate processes; apical part of inner side with short thick process; outer margin broadened abruptly at apex, outer apical angle arc-shaped, with several small toothlike processes.
