Wilson J. E. M. Costa, Rogério Suzart and Dalton T. B. Nielsen: Cynolebias paraguassuensis n. sp. (Teleostei: Cyprinodontiformes: Rivulidae), a new seasonal killifish from the Brazilian Caatinga, Paraguaçu River basin, pp. 129-132

Abstract
Cynolebias paraguassuensis n. sp., a median sized species from the Paraguaçu River basin, northeastern Brazil, is described, constituting the first record of a rivulid fish for that basin. It is similar to C. itapicuruensis and C. vazabarrisensis in having dentary teeth strongly bowed. It is distinguished from C. itapicuruensis and C. vazabarrisensis in possessing a longer pectoral fin in males and light blue dots over the entire anal fin in males.
