Celaetycheus vatapa new species

Figures 13 , 14–15

Type material. Male holotype and female paratype from Estação Ecológica Wenceslau Guimarães, Wenceslau Guimarães [13°34ʹ50ʺS, 39°42ʹ17ʺW] 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 13A–B ) resemble those of C. bobo sp. nov. ( Figs 9A–B ) 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. 13A ). Females of C. vatapa sp. nov. ( Figs 13C–D ) resemble those of C. caruru sp. nov. ( Figs 10C–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. 13C ).

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 v2-2 -2-2-2, p1-1, r1-1, metatarsus II v2-2 -2, p1-1-1, r1-1-1. Palpal trochanter with short apical spines; coxa of leg I covered in the ventral area with short and thick spines ( Fig. 14 D). Palp ( Figs 13A–B ): 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 v2-2 -2-2-2, p0, r0, III v2-2 -2, p1-1, r1-1, IV v1 p-1p-2, p1-1, r1-1; metatarsus I–II v2-2 -2, p0, r0, III–IV v2-2 -2, p1-1-1, r1-1-1. Epigynum ( Figs 13C–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. 15 C).
