The specific name is a noun in apposition taken from the type locality. Diagnosis . The male pedipalp resembles the general conformation of F. p el t a Platnick, 1975 , F. pulchra and F. maldonado Platnick, Grismado & Ramírez, 1999 by the laminar expansion of the embolus; however, in these species the expansion is prolateral, and the embolus has a basal ledge (see Platnick 1975 , figs 86, 87; Platnick et al . 1999 , figs 19–21; Piacentini et al . 2013 , figs 6c–e;). F. jurubatiba sp. n. is distinguished by having the laminar extension on the retrolateral side of the embolus, and by lacking the basal ledge ( Figs 5 h–j, 6b–c). The female internal genitalia have large, rounded spermathecae as in F. p e l t a , but can be distinguished by having more inflated spermathecae which touch each other medially ( Fig. 6 a). Description . Male ( holotype ). Total length 1.87. Carapace 0.93 long, 0.69 wide. Femur I 0.79 long, 0.19 high. Posterior median eyes separated by slightly more than their diameter ( Fig. 5 e). Paturon with inconspicuous lateral ridge. Sclerotized portions of body orange brown ( Fig. 5 e–g); abdominal scutum covering two-thirds of dorsum. Unsclerotized portion of abdomen with a dorsal, purplish brown pattern on a yellow background, forming a yellow ring close to the pedicel ( Fig. 5 e–g). Pedipalpal femur not thickened, tibia globose and almost the same size as the palpal bulb; bulb relatively small, half the length of the cymbium; embolus base rounded, without any ledge, distal half flattened with a retrolateral translucent extension with an irregularly shaped, slightly more sclerotized area ( Figs 5 h–j, 6b–c).

Female ( paratype ). Total length 2.51. Carapace 1.12 long, 0.80 wide. Femur I 0.89 long, 0.22 high. Leg I with sparse prolateral scopula on tibia, metatarsus and tarsus ( Fig. 9 a, b). Eyes and chelicerae as in male. Sclerotized portions of body orange brown ( Fig. 5 a–c); abdominal scutum orange brown with lateroventral notches where two oblique, elongated ventral plates (postepigastric scutes) fit, converging posteriorly toward middle of venter, but not touching ( Fig. 5 d). Unsclerotized portion of abdomen as in male ( Fig. 5 a–c). Tarsus I without tenent setae ( Fig. 9 a– c), tarsi II–IV with weak claw tufts, those of leg IV composed of only two pseudotenent setae on each side ( Fig. 9 d–g). Internal genitalia with two large, rounded spermathecae, touching each other medially, bearing conspicuous paired poreplates close to each other ( Fig. 6 a). Distribution . Known only from the type locality.
