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.

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.
