Type material. Male holotype from Estação Ecológica Pau Brasil, Porto Seguro [16°27ʹ0 0ʺS, 39°03ʹ54ʺW], 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°27ʹ0 0ʺS, 39°03ʹ54ʺW], 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 10A–B ) 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 10C–D ) resemble those of C. bobo sp. nov. ( Figs 9C–D ) by the subtriangular shape of the median sector of epigynum, but can be distinguished by having this shorter ( Fig. 10C ).
