Mollusca, Bivalvia, Cuspidariidae, <i>Plectodon braziliensis</i> (E. A. Smith, 1915) n. comb.: Record of the genus for the South Atlantic, off Brazil.

Abstract

An analysis of bivalves shells collected off the coast of Rio Grande, Rio Grande do Sul, Brazil and specimens ofscientific collections, identified as Cuspidaria braziliensis E. A. Smith, 1915 was made. From the examination of syntypes ofC. braziliensis and the type species of the genus Plectodon Carpenter, 1864, a redescription was made and it is proposed totransfer the species to the genus Plectodon, resulting in the new combination Plectodon braziliensis (E.A. Smith, 1915). Thisis the first record of a Plectodon species for the South Atlantic.
