The female is similar to F . jurubatiba by the habitus, size and by the shape of the spermathecae, which are globose and contiguous, but can be distinguished by the more expanded anterior portion of the spermathecae ( Fig. 8 a).

Description . Male. See Ramírez and Grismado (1996) . Aditional notes: the male pedipalp of the Macaé specimens differs from the type material by the position of the embolus in a more retrolateral position, forming a wider angle with the cymbium, and by the shape of the tibia, which is slightly larger relative to the bulb ( Figs 7 h–j, 8b–c). While the copulatory bulb may be rotated due to a partial expansion of the basal hematodocha, we interpret the size of the tibia as intraspecific variability. Female (Macaé, MNRJ 06818). Total length 3.00. Carapace 1.37 long, 0.99 wide. Femur I 1.37 long, 0.33 high. Eyes and chelicerae as in male. Sclerotized portions of body as in male ( Fig. 7 a–c); abdominal scutum orange, with lateroventral notches where two oblique, elongated ventral plates (postepigastric scutes) fit, converging posteriorly toward middle of venter, but not touching ( Fig. 7 d). Unsclerotized portion of abdomen as in male ( Fig. 7 a–c). Internal genitalia composed of two large oval spermathecae, touching each other medially, with the anterior portion expanded, bearing conspicuous paired poreplates close to each other ( Fig. 8 a). Distribution . Brazil , in the state of Rio de Janeiro, and known from Rio de Janeiro, Casimiro de Abreu and Macaé.
