Abstract

Twenty-one species of Aaptos Gray, 1867 are known world-wide, of which only three were reported from Brazil. Two new species of this genus are here described from the Brazilian coast (Potiguar Basin, Northeastern Brazil): A. hajdui sp. nov. and A. potiguarensis sp. nov. Both possess only one category of strongyloxeas and one of styles, although both with wide size variation, suggesting that the diagnosis of the genus should be revised. Previous Brazilian records of A. aaptos have their status re-evaluated here, and only three species of the genus can be considered valid in Brazil: A. glutinans, A. hajdui sp. nov. and A. potiguarensis sp. nov.
