Etymology. “ Aberém ” is a typical meal of the Bahia culinary tradition and also plays a role in the religious ritual of Candomblé. It is made with macerated corn or rice and cooked in banana leaves.

Diagnosis. Males of Celaetycheus aberem sp. nov. (Figs 6A–B) resemble those of C. mungunza sp. nov. (Figs 12A–B) by the large embolus, absence of a tegular projection and a median apophysis curved prolaterally at tip, but can be distinguished by the larger median apophysis (Fig. 6A). Females of C. aberem sp. nov. (Figs 6C–D) can be distinguished from the remaining species of the genus by the subquadrangular shape of the median sector of the epigynum (Fig. 6C).
