Identification. Our material of this genus was identified based on the key provided by Floriano et al. (2017). The females above lack spines on the humeral angles ( Fig. 12A); have the stridulatory structure on the lateral margin of the abdominal laterotergites formed by a row of tightly packed minute pegs ( Fig. 12D); the first three vis- ible abdominal segments with transverse lateral sulci; the hind femur incrassate, about two times wider than the middle femur, with a spine on the distal two-thirds of the posterior margin distinctly larger than others ( Fig. 12A); and the dorsum of abdominal segment VIII without projections.

Distribution in Brazil. TO, MA*, MT, MS, MG.
