Diagnosis. 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.
