Figs 13C–13D , 14E–14H

Type material. Holotype: ♂ from Reserva Particular do Patrimônio Natural Canguçu , Centro de Pesquisa Canguçu, Pium, Tocantins, Brazil (9.977°S 50.085°W), 18.V.2016, leg. A.B. Bonaldo et al. (MPEG 39057).

Etymology. The epithet, to be treated as a Latin adjective, was built based on the type locality.

Diagnosis. 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 ).

Description. Male holotype. Total length: 2.4. Carapace dark brown, with cephalic region black ( Fig. 13C ); 1.3 long, 0.98 wide, 0.74 high. Ocular quadrangle 0.69; anterior eye row 1.08, posterior 0.93 wide. Chelicera and labium dark brown, endite and sternum light brown ( Fig. 13D ). Leg formula: 3142; length of legs: I 2.59 (0.84 + 0.36 + 0.62 + 0.46 + 0.31), II 2.26 (0.70 + 0.29 + 0.60 + 0.41 + 0.26), III 2.61 (0.84 + 0.36 + 0.53 + 0.57 + 0.31), IV 2.50 (0.72 + 0.29 + 0.53 + 0.60 + 0.36). Legs: femora, patellae and tibiae I–IV dark brown; metatarsi and tarsi yellow. Tibia I macrosetae well developed, with tips of a more proximal pair surpassing insertions of the spines of a more distal pair. Abdomen dorsally dark brown with pairs of light brown circular spots ( Fig. 13C ); ventrally dark brown ( Fig. 13D ). Spinnerets dark brown.

Female. Unknown.

Distribution. Known only from the type locality (Tocantins, Brazil) ( Fig. 23 ).
