Our specimens were identified based on the following characters: antennomere I shorter than II and III together; eye not surpassing the anterolateral angle of the pronotum; pronotum with apex rounded, reaching the mesoacetabulum in the apterous form ( Fig. 5A ); dorsum of acetabula with silvery setae ( Fig. 5A, C ); fore femur robust and slightly arched, with sparse conical black setae ventrally ( Fig. 5B ); and male abdominal segment VIII in natural position with about half of its length exposed ( Fig. 5B, D ). This combination of characters distinguishes them from all known congeners ( Cordeiro 2017 ). Distribution in Brazil . AM, PA, MA*, CE, BA, MT, MG, SP, RJ.
