Identification. Our material was identified based on the key provided by Floriano et al. (2017). The two specimens above have pronotal humeral angles rounded, not spinose; stridulatory structure on laterotergites formed by a row of widely separated knob-like denticles; and hind femur incrassate, about 2.5 times wider than middle femur, with a spine on distal two-thirds of posterior margin distinctly larger than others. The male has the venter of abdominal segment VIII centrally expanded, but not forming a lobule, and the female has short posterior projections on the dorsum of abdominal segment VIII, with about one-third the length of the segment at midline.

Known distribution. Argentina, Bolivia, Brazil, Guyana, Paraguay, Peru, Venezuela ( Floriano et al 2017).
