Our males of R. robusta were identified based on the pronotum long, completely covering the mesonotum, mostly blackish, strongly contrasting with a yellowish-brown mark on the anterior lobe ( Fig. 11I ); jugum and proepisternum with minute black denticles; the hind trochanter with spines; the hind femur with three irregular rows of spines, with a large spine near its middle dorsally displaced from the others; and the sides of abdominal segment VII without patches of black denticles ( Magalhães et al. 2016 ). Females were associated with males from the same locality based on the general appearance and by comparison with reference material from other Brazilian states. Figure 12.
