Identification. Like R. hambletoni , R. tenuipes belongs to the angustipes complex of species ( Polhemus 1997). Our males could be distinguished from R. hambletoni by the abdominal laterotergites bowed laterally and the longer hind femur, slightly longer than half of the body length ( Fig. 11M). Females of R. tenuipes were easily distinguished from those of R. hambletoni based on the laterotergites not reflected over the mediotergites ( Fig. 11O) and the hind femur with at least seven spines (Moreira 2012).

Distribution in Brazil. RR, AM, PA, MA*, MT, MS, MG, ES, SP, RJ.
