PARAENSE W. L.
A redescription of conchological and anatomical characters of the planorbid mollusc Plesiophysa ornata (Haas, 1938) is presented, based on topotypic material and specimens from 14 additional localities in the Brazilian states of Rio Grande do Norte, Paraíba, Sergipe, Bahia, Espírito Santo and Minas Gerais. Due to the close similarity of their shells, a sure discrimination of the five species of Plesiophysa described so far (P. pilsbryi, P. granulata, P. guadeloupensis, P. ornata and P. hubendicki) is only possible through their anatomical features. The present study points to the high probability of synonymy of P. hubendicki with P. ornata. Investigations on the anatomy of P. pilsbryi and P. guadeloupensis are needed to define their taxonomic relation with the other nominal species.
