Body varies in length from 1.8 to 2.3mm and is mainly dark brown. The basal half of antennal segment 3, the apices of the fore tibiae and the fore tarsi are yellowish brown. The bases of the fore wings are light brown, but otherwise the wings are colourless. The head is longer than wide and the dorsal surface is transversely striate. Ocelli are present, and the postocular setae are moderately short. Antennal segment 3 has 1 outer sense cone while segment 4 has 2 outer and 2 inner sense cones. Antennal segment 7 has a broad pedicel, and the mouth cone is short and rounded. The anteromarginal and lateral setae on the prothorax are small. Each fore tarsus has a short but stout tooth, which is larger in males. The pelta is triangular and has elongate hexagonal reticulations. Abdominal tergite 9 has moderately sized, pointed major setae, and the tube is short. The glandular area on sternite 8 of males is absent (Stannard 1968).
