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 5A–B) resemble those of C. flavostriatus (Figs 1A–B) 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. 11C) 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. 5D).
