The elytra are angled at their point of contact with the pronotum such that they appear confluent with the posterior margin of the pronotum. The elytral setae are arranged in regular rows, and are small, subrecumbent, and brown. The spermatheca is distinct, with the ramus basally tapered, and the corpus possessing an annulate, cylindrical projection nearly 1/2
