Description
Summary:A new species of Dasyatis is described from the southwestern Atlantic, off northeastern Brazil. It differs from its congeners by its relatively large eyes, presence of well-developed dorsal and ventral finfolds on tail ending approximately on the same vertical line, dorsal and ventral color patterns, and possession of distinct ventral markings on disc. Adults are apparently associated with coral or sandstone reefs. Uma nova espécie de Dasyatis é descrita do Atlântico ocidental, da costa nordeste do Brasil. Ela difere de suas congêneres pelos olhos relativamente grandes, pela presença de membranas dorsais e ventrais bem desenvolvidas na cauda, terminando aproximadamente na mesma linha vertical, pelo padrão de colorido dorsal e ventral, e por possuir manchas distintas ventrais no disco. Adultos são aparentemente associados a recifes coralinos ou areníticos.
