The genus Dasyatis Rafinesque, 1810 ZBK comprises 37 species and occurs worldwide (Compagno, 1999a,b and Gomes et al. 2000). Six species of Dasyatis ZBK have been reported for the southwestern Atlantic (in Brazilian waters): the southern stingray, D. americana Hildebrand & Schroeder, 1928 ZBK ; the roughtail stingray, D. centroura (Mitchill, 1815) ; the wingfin stingray, D. geijskesi Boeseman, 1948 ZBK ; the longnose stingray D. guttata (Bloch & Schneider, 1801) ; the Brazilian large-eyed stingray, D. marianae Gomes, Rosa & Gadig, 2000 ZBK , and the bluntnose stingray, D. say (Lesueur, 1817) . The other dasyatid stingrays known from Brazil are: the pelagic stingray, Pteroplatytrygon violacea (Bonaparte, 1832) and the chupare stingray, Himantura schmardae (Werner, 1904) (Dasyatidae) (Ribeiro, 1907, 1923; Figueiredo, 1977; Charvet-Almeida et. al., 2000, Gomes & Gadig, 2003). The Atlantic stingray D. sabina (Lesueur, 1824) , according to Garman (1913), has been recorded from North Carolina (USA) to Brazil. Bigelow & Schroeder (1953: 376), cited the Brazilian record of this species, referring to it as "... probably not on good evidence". Herein we describe a new species of Dasyatis ZBK from Marajó Bay, state of Pará , northern Brazil.
