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.
