Type material. Male holotype from Coaraci (Fazenda Boa Esperança) [14 ° 38 ʹ 27 ʺS, 39 ° 33 ʹ0 3 ʺW], 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 ° 17 ʹ0 2 ʺS, 39 ° 50 ʹ 34 ʺW], Bahia, Brazil, I. 1978, deposited in IBSP 163489; 1 male and 1 female from Jequié [13 ° 51 ʹ 28 ʺS, 40 °05ʹ0 2 ʺW], 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 7 A –BView FIGURE 7. A – D) resemble those of C. bobo  sp. nov. ( Figs 9 A –BView FIGURE 9. A – D) 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. 7 AView FIGURE 7. A – D). Females of C. acaraje  sp. nov. ( Figs 7 C –DView FIGURE 7. A – 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.
