Figs 15C–15D , 16E–16H

Type material. Holotype: ♂ from Estação Ecológica de Jureia-Itatins (Núcleo Arpoador), Peruíbe, São Paulo, Brazil (24.387°S, 47.017°W), 21–26.IV.2012, G.H.F. Azevedo & J.P.P. Pena-Barbosa leg. (UFMG 13046).

Etymology. Epithet, a noun in apposition, is due to the shape of the embolus tip, reminiscent of a typical planarian head.

Diagnosis. The male of R. planaria sp. nov. is similar to those R. otti sp. nov. and R. barbado sp. nov. for having a thin embolus with an apical twist ( Fig. 16G ), but differs for being shorter.

Description. Male holotype. Total length: 2.45. Carapace dark brown, cephalic region black ( Fig. 15C ); 1.38 long, 0.96 wide, 0.70 high. Ocular quadrangle 0.69; anterior eye row 1.03, posterior 0.84 wide. Chelicera, labium and sternum dark brown, endite light brown ( Fig. 15D ). Leg formula: 1342; length of legs: I 2.52 (0.84 + 0.38 + 0.65 + 0.42 + 0.23), II 1.95 (0.65 + 0.27 + 0.42 + 0.38 + 0.23), III 2.47 (0.84 + 0.38 + 0.49 + 0.53 + 0.23), IV 2.45 (0.77 + 0.38 + 0.50 + 0.57 + 0.23). Legs: femora I–IV, patellae and tibiae light brown; metatarsi I–III yellow, IV light brown; 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 light brown, with proximal pair of tufts of white scales and another pair on posterior half ( Figs 15C–15D ); ventrally light brown. Spinnerets light brown.

Female. Unknown.

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