Otiothops goytacaz View in CoL sp. n.

( Figs 3–4 View FIGURE 3 View FIGURE 4 )

Type material. Holotype male, TECAB, 22°17’08”S, 41°43’54”W, Macaé, Rio de Janeiro, Brazil, 25–30 March 2010, Atlantic Rainforest fragment, pitfall trap, elevation 30 m, R. Baptista, V. Brandão, D. Castro, M. da Costa, G. Cardoso, A. Pinto, A. Pérez, G. Marquez ( MNRJ 06811). Paratype: 1 female, same data as holotype except Parque Nacional da Restinga de Jurubatiba , 22°17’14”S, 41°41’56”W, restinga ( MNRJ 06812).

Other material examined. BRAZIL: Rio de Janeiro: Macaé: 1 female, TECAB, 22°17’08”S, 41°43’54”W, 18 March 2011, Atlantic Rainforest fragment, litter, elevation 30 m, R. Baptista ( UFRJ MAC 1081); 1 male, same data except 28 September 2012, D. Pedroso ( UFRJ MAC 1511); 1 male and 1 female, same data except 23 May 2013, G. Miranda ( UFRJ MAC 4746).

Etymology. The specific name is a noun in apposition taken from the native free people that used to live in the region around the type locality, prior to European colonization during the 16th century.

Diagnosis. The male pedipalp is similar to that of Otiothops hoeferi Brescovit & Bonaldo, 1993 by the straight and flattened embolus ( Brescovit and Bonaldo 1993, figs 7–8), but can be distinguished by the thin and posteriorly curled extension at the apex of the embolus ( Figs 3 View FIGURE 3 h–j, 4b–c). The female vulva ( Fig. 4 View FIGURE 4 a) is similar to that of O. atalaia ( Fig. 2 View FIGURE 2 a) by having an anteromedian projection, but this structure is relatively shorter than in O. atalaia . The median receptacles (although collapsed in the preparation of Fig. 4 View FIGURE 4 a) are smaller than in O. atalaia and show no traces of the smaller anterodorsal diverticula, and the anterior sclerotized area has conspicuous, paired poreplates ( Fig. 4 View FIGURE 4 a).

Description. Male (holotype). Total length 3.86. Carapace 1.76 long, 1.18 wide. Femur I 1.22 long, 0.57 high. Posterior median eyes touching ( Fig. 3 View FIGURE 3 e). Paturon with inconspicuous lateral ridge. Sclerotized portions of body reddish dark brown; abdominal scutum orange brown, unsclerotized portion of dorsal abdomen purplish brown with yellow dots, ventral abdomen lighter and almost uniformly yellow ( Fig. 3 View FIGURE 3 e–g). Tarsi II–IV with claw tufts. Pedipalpal femur not thickened ventrally at middle, tibia nearly cup-shaped and almost one-third palpal bulb size; bulb large and inflated, as long as cymbium; embolus almost as long as cymbium, with thin, posteriorly curled extension at apex ( Figs 3 View FIGURE 3 h–j, 4b–c).

Female (paratype). Total length 5.67. Carapace 2.11 long, 1.50 wide. Femur I 1.56 long, 0.70 high. Eyes and chelicerae as in male. Cephalothorax and leg I lighter than male ( Fig. 3 View FIGURE 3 a–c). Abdominal scutum small, entire, with a V-shaped sclerite behind epigastric furrow (postepigastric scutum) ( Fig. 3 View FIGURE 3 d), unsclerotized portion of abdomen as in male ( Fig. 3 View FIGURE 3 a–c). Tarsi II–IV with claw tufts. Internal genitalia composed of two globose median receptacles basally joined (although collapsed in the preparation) ( Fig. 4 View FIGURE 4 a). Anteriorly directed from the receptacles there is a longer than wide median structure (anteromedian projection), probably an apodeme; paired poreplates, discoid shaped, present.

Distribution. Known only from the type locality.
