The male of R. tocantinensis sp. nov. is similar to those of R. cotriguacuensis sp. nov. and R. ruizi (Zhang & Maddison, 2012) comb. nov. by having a short and wide embolus, projecting from the prolateral region of the tegulum and partially covered by a membranous layer (Fig. 14G), but differs from them by having an apical constriction in the embolus, and by a robust RTA directed toward the center of the tegulum (Fig. 14H).
