Type material. Male holotype from Estação Ecológica Pau Brasil, Porto Seguro [16 ° 27 ʹ0 0ʺS, 39 °03ʹ 54 ʺW], Bahia, Brazil, 18.IV. 1998, A.D. Brescovit et al., deposited in IBSP 17826. Paratypes: 1 male and 1 female, same data as the holotype, 20.IV. 1998, deposited in IBSP 17944 and 17952; 1 female, same data as the holotype, 19.IV. 1998, deposited in IBSP 17915.

Additional material examined. BRAZIL: Bahia. Porto Seguro, Estação Ecológica Pau Brasil [16 ° 27 ʹ0 0ʺS, 39 °03ʹ 54 ʺW], 2 females, 18.IV. 1998 (IBSP 17913, 17723); 2 males and 1 female, 20.IV. 1998 (IBSP 17796, 17842), all collected by A.D. Brescovit et al.

Etymology. “ Caruru  ” is a typical meal of the Bahia culinary tradition and also plays a role in the religious ritual of Candomblé. It is made with okra, pepper, dried shrimp and “dendê” palm oil. It can be consumed with “ Acarajé  ” and beef, fish or chicken.

Diagnosis. Males of Celaetycheus caruru  sp. nov. ( Figs 10 A –BView FIGURE 10. A – D) can be distinguished from the remaining species of the genus by the presence of an additional elongated projection on the median apophysis. Females of Celaetycheus caruru  sp. nov. ( Figs 10 C –DView FIGURE 10. A – D) resemble those of C. bobo  sp. nov. ( Figs 9 C –DView FIGURE 9. A – D) by the subtriangular shape of the median sector of epigynum, but can be distinguished by having this shorter ( Fig. 10 CView FIGURE 10. A – D).
