Additionally, new records from Brazilian caves are provided for Cryptachaea parana, from the states of Tocantins, Goiás, Minas Gerais, Mato Grosso do Sul and São Paulo; C. schneirlai and C. alacris from the state of Pará; C. dea (Buckup Marques, 2006) and C. rioensis (Levi, 1963) from Pará and Minas Gerais, C. jequirituba (Levi, 1963) from Minas Gerais and C. benivia from São Paulo.
