Figures 12 , 14–15

Type material. Male holotype and female paratype from Camacan [15°25ʹ0 8ʺS, 39°29ʹ45ʺW], Bahia, Brazil, deposited in IBSP 163263. Female paratype, same data as holotype, deposited in IBSP 163264.

Diagnosis. Males of Celaetycheus mungunza sp. nov. ( Figs 12A–B ) can be distinguished from the remaining species of the genus by the shape of the median apophysis, with a large base and a short and curved tip. Females of C. mungunza sp. nov. ( Figs 12C–D ) can be distinguished from the remaining species of the genus by the subtriangular median sector of the epigynum, with a median constriction and truncated posteriorly.

Etymology. “ Mungunzá ” is a typical dessert of the Bahia culinary tradition and also plays a role in the religious ritual of Candomblé and Umbanda. It is made with white corn baked in water, milk or coconut milk, covered with cinnamon.
