There are 2 or 3 pairs of ocellar setae, and the postocular setae are small. Antennae are 8 segmented, and segment 3 is stout with the external margin produced into a tooth. Antennal segment 3 has a simple sense cone, and segment 4 has a forked sense cone. The pronotum has 1 pair of long posteroangular setae, and 3 pairs of setae along the posterior margin. The metanotum has reticulate sculpture, and a pair of campaniform sensilla. The meso- and metafurca lack spinulae. Females are macropterous, and males are apterous. The first vein on the forewings has 2 setae on the distal half, and the second vein has approximately 10 setae. Tergite 10 has a pair of stout, thorn-like setae (Moritz et al., 2001).
