Etymology. “ Abará  ” 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) and served with pepper, dried shrimp, “ Vatapá  ”, “ Caruru  ” or salad. It is similar to “ Acarajé  ”, but baked instead of fried.

Diagnosis. Males of Celaetycheus abara  sp. nov. ( Figs 5 A –BView FIGURE 5. A – D) resemble those of C. flavostriatus  ( Figs 1 A –BView FIGURE 1. A – D) by the shape of the embolus, but can be distinguished by the thin embolus and truncated retrolateral cymbial projection. Females of Celaetycheus abara  sp. nov. resemble those of C. flavostriatus  ( Fig. 11 CView FIGURE 11. A – D) by the elongate median sector and the presence of lateral lobes in the lateral sectors of the epigynum, but can be distinguished by the smaller head of spermathecae ( Fig. 5 DView FIGURE 5. A – D).
