Anhembia: a new genus from the Passa Dois Group - Permian

Abstract

The restudy of specimens of bivalves of the Passa Dois Group (Permian) formerly referred by MENDES (1949) to the genus Leinzia and of new specimens collected in the State of São Paulo has led the authors to propose a new genus, Anhembia, for two of the species previously assigned to that genus, A. froesi and A. gigantea, both of which from the lower section of the Corumbataí Formation of the state of São Paulo (equivalent to the Serra Alta Facies in the states of Paraná and Santa Catarina).
