Type material. Male holotype from Coaraci (Fazenda Boa Esperança) [14°38ʹ27ʺS, 39°33ʹ0 3ʺW], Bahia, Brazil, 17.I.1970, CEPLAC, deposited in MNRJ 13379. Paratypes: 2 females, same data as holotype, deposited in IBSP 163490 and MNRJ; 1 male from Itagibá [14°17ʹ0 2ʺS, 39°50ʹ34ʺW], Bahia, Brazil, I.1978, deposited in IBSP 163489; 1 male and 1 female from Jequié [13°51ʹ28ʺS, 40°05ʹ0 2ʺW], Bahia, Brazil, VII.2006, L. Boccardo, deposited in IBSP 163251.

Etymology. “ Acarajé ” is a typical meal of the Bahia culinary tradition and also plays a role in the religious ritual of Candomblé. It is made with a special type of bean (fradinho), onions and salt, fried in a special palm oil (“dendê” oil from the Elaeis guineensis Jacq. ). The meal is served with pepper, dried shrimp, “ Vatapá ”, “ Caruru ” or salad.

Diagnosis. Males of Celaetycheus acaraje sp. nov. ( Figs 7A–B ) resemble those of C. bobo sp. nov. ( Figs 9A–B ) by the straight median apophysis and with a ventral cup-shaped projection, but can be distinguished from C. bobo by the thinner embolus and presence of a small additional tegular projection ( Fig. 7A ). Females of C. acaraje sp. nov. ( Figs 7C–D ) can be distinguished from the remaining species of the genus by the narrow median sector of the epigynum, elongated and strongly constricted in the median area and by the large fertilization ducts.
