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.
