Pleonal somite 2 overlapping somites 1 and 3, variable in size. Telson sharp in lateral view, with apparent square tip in dorsal view; tip with setae; with 2 pairs of movable spines dorsally. Uropodal endopod and exopod narrow, much longer than wide; exopod inner margin weakly serrate, outer margin with setal pits. Third maxillipeds shorter than pereiopods 3–5. Pereiopods 1 and 2 shorter and with more bulbous articles than pereiopods 3–4. Type species . Atyoida roxoi Beurlen, 1950 , by present designation. Type age . Lower Cretaceous (Aptian) . Etymology . The genus name is derived from the state of Bahia in Brazil , where the specimen was collected, and ‘caris’, from the Greek for crab, a common stem in the group. Gender: feminine. Remarks . A full description and stratigraphic account of Bahiacaris n. gen. is given by Schweitzer et al. (2019) .
