Living bivalves of the family Mactridae from Northern Argentina and Uruguay are herein revised. A bibliographical research yielded 22 nominal species reported from this area. Material from several institutions as well as fieldwork from La Paloma, Uruguay to San Blas, Argentina were studied. In addition, all type material are illustrated and redescribed. Descriptions of the soft and hard parts including ultrastructure of the shell, hinge and ligament using the Scanning electronic microscope (SEM) were carried out. We consider Mactra guidoi, M. isabelleana, M. marplatensis, M. petitii, Micromactra janeiroensis, Raeta plicatella and Darina solenoides as valid species. In addition, a list of synonyms as well as the corroborated distribution is proposed for each species.
