Figures 13View FIGURE 13. A – D, 14– 15View FIGURE 14View FIGURE 15

Type material. Male holotype and female paratype from Estação Ecológica Wenceslau Guimarães, Wenceslau Guimarães [13 ° 34 ʹ 50 ʺS, 39 ° 42 ʹ 17 ʺW] Bahia, Brazil, 23.X. 2010, D. Polotow et al., deposited in IBSP 162604. Paratypes: 7 females, same data as holotype, deposited in IBSP 162609.

Etymology. “ Vatapá  ” is a typical meal of the Bahia culinary tradition. It is a cream made with breadcrumbs, cornmeal, ginger, pepper, peanut, cashew nut, coconut milk, “dendê” palm oil, onions and tomatoes, served with rice and dried shrimp or fish.

Diagnosis. Males of Celaetycheus vatapa  sp. nov. ( Figs 13 A –BView FIGURE 13. A – D) resemble those of C. bobo  sp. nov. ( Figs 9 A –BView FIGURE 9. A – D) by having the male palp with the median apophysis straight and with a ventral cup-shaped projection, but can be distinguished by the thinner embolus and thinner median apophysis ( Fig. 13 AView FIGURE 13. A – D). Females of C. vatapa  sp. nov. ( Figs 13 C –DView FIGURE 13. A – D) resemble those of C. caruru  sp. nov. ( Figs 10 C –DView FIGURE 10. A – D) by the subtriangular shape of the median sector, but can be distinguished by the presence of lateral lobes on the lateral fields of the epigynum ( Fig. 13 CView FIGURE 13. A – D).

Description. Male (holotype IBSP 162604). Total length: 4.1. Carapace 2.3 long, 2.0 wide. Eye diameters: AME 0.11 / ALE 0.09 / PME 0.18 / PLE 0.19. Leg measurements: I: absent; II: femur 2.2 / patella 0.9 / tibia 1.9 / metatarsus 2.0/ tarsus 0.9 / total 7.9; III: absent; IV: absent. Leg spination: tibia II v 2 - 2 - 2 - 2 - 2, p 1 - 1, r 1 - 1, metatarsus II v 2 - 2 - 2, p 1 - 1 - 1, r 1 - 1 - 1. Palpal trochanter with short apical spines; coxa of leg I covered in the ventral area with short and thick spines ( Fig. 14View FIGURE 14 D). Palp ( Figs 13 A –BView FIGURE 13. A – D): tibia straight, with almost the same length as the cymbium; retrolateral tibial apophysis short and coniform; ventral tibial apophysis thin; embolus long; additional tegular projection short; retrolateral cymbial projection truncated.

Female (paratype IBSP 162604). Total length 3.9. Carapace 2.1 long, 1.7 wide. Eye diameters: AME 0.1 / ALE 0.08 / PME 0.20 / PLE 0.20. Leg measurements: I: femur 1.7 / patella 0.8 / tibia 1.6 / metatarsus 1.95 / tarsus 0.6 / total 6.65; II: 1.7 / 0.7 / 1.4 / 1.4 / 0.7 / 5.9; III: 1.6 / 0.65 / 1.25 / 1.5 / 0.7 / 5.7; IV: 2.0/ 0.7 / 1.75 / 2.2 / 0.9 / 7.55. Leg formula 4132. Leg spination: tibia I –II v 2 - 2 - 2 - 2 - 2, p0, r0, III v 2 - 2 - 2, p 1 - 1, r 1 - 1, IV v 1 p- 1 p- 2, p 1 - 1, r 1 - 1; metatarsus I –II v 2 - 2 - 2, p0, r0, III –IV v 2 - 2 - 2, p 1 - 1 - 1, r 1 - 1 - 1. Epigynum ( Figs 13 C –DView FIGURE 13. A – D): copulatory ducts curved; head of spermathecae round; base of spermathecae smooth; fertilization ducts short and thin.

Distribution. Wenceslau Guimarães, State of Bahia, northeast Brazil ( Fig. 15View FIGURE 15 C).
