Grass (Chiasson, 1986).
The body varies around 2.5mm in length, and is blackish brown. The legs are yellowish, antennal segment 1 and the basal two thirds of segment 2 are concolourous with the head. The first third of segment 2, all of segments 3 and 4, and the basal half of segment 5 are concolorous with the legs. The apical one half to one third of segment 5 and the remaining segments are concolorous with the head. The head is longer than wide and slightly produced in front of the eyes. The dorsum of the head is somewhat subreticulate along the base and sides, and the cheeks are serrated. Antennal segment 3 has 1 inner and 1 outer sense cone, segment 4 has 2 inner and 2 outer sense cones. The mouth cone is short and broadly rounded. The pronotum is about 0.6 the length of the head, and nearly smooth, with few striae along the lateral and posterior margins. The tube is about 0.8 the length of the head (Thomasson and Post, 1966).
