description: This dataset contains the digitized treatments in Plazi based on the original journal article Wilson J. E. M. Costa (2007): Taxonomy of the plesiolebiasine killifish genera Pituna, Plesiolebias and Maratecoara (Teleostei: Cyprinodontiformes: Rivulidae), with descriptions of nine new species. Zootaxa 1410: 1-41, URL: http://www.zoobank.org/urn:lsid:zoobank.org:pub:A1E8EDF5-B267-4CB6-9206-9F014134DFF2AbstractThe seasonal plesiolebiasine killifish genera Pituna Costa, Plesiolebias Costa, and Maratecoara Costa, endemic to central and northeastern Brazil, are revised. A key is provided for the identification of plesiolebiasine genera, and keys are also included for species of the three revised genera. Six species are recognized in Pituna: P. brevirostrata n. sp. from the rio Paranaiba drainage, rio Parana basin; P. poranga Costa from the rio Araguaia basin; P. compacta Myers from the rio Tocantins basin; P. schindleri n. sp. from the rio Parnaiba basin; P. obliquoseriata n. sp. from the rio das Mortes drainage; and P. xinguensis Costa & Nielsen n. sp. from the rio Xingu basin. Four new species of Plesiolebias are described, complementing a recent revision of the genus (Costa, 1998c): P. fragilis n. sp., from the middle rio Araguaia basin; P. altamira Costa & Nielsen n. sp., from the rio Xingu basin; P. filamentosus Costa & Brasil n. sp., from the rio Tocantins floodplains; and P. canabravensis Costa & Nielsen n. sp., from the rio Canabrava floodplains, rio Tocantins basin. Three species are recognized in Maratecoara: M. lacortei (Lazara), from the Araguaia-das Mortes basin; M. formosa Costa & Brasil, from the middle rio Tocantins floodplains; and M. splendida n. sp. from the rio Canabrava floodplains, rio Tocantins basin.Key words: Killifishes, Pituna, Plesiolebias, Maratecoara, Neotropical, Systematics, new speciesResumoOs generos de plesiolebiasineos sazonais Pituna Costa, Plesiolebias Costa e Maratecoara Costa, endemicos do centra e nordeste do Brasil, sao revisados. E fornecida uma chave para a identificacao de generos plesiolebiasineos e chaves tambem sao incluidas para especies dos tres generos revisados. Seis especies sao reconhecidas em Pituna: P. brevirostrata sp. nov. da drenagem do rio Paranaiba, bacia do rio Parana, P. poranga Costa da bacia do rio Araguaia, P. compacta Myers da bacia do rio Tocantins, P. schindleri sp. nov. da bacia do rio Parnaiba, P. obliquoseriata sp. nov. da drenagem do rio das Mortes e P. xinguensis Costa & Nielsen sp. nov. da bacia do rio Xingu. Quatre novas especies de Plesiolebias sao descritas, complementando-se uma recente revisao do genero (Costa, 1998c): P. fragilis sp. nov. da bacia do medio rio Araguaia, P. altamira Costa & Nielsen sp. nov. da bacia do rio Xingu, P. filamentosus Costa & Brasil sp. nov. da varzea do rio Tocantins e P. canabravensis Costa & Nielsen sp. nov. da varzea do rio Canabrava, bacia do rio Tocantins. Tres especies sao reconhecidas em Maratecoara: M. lacortei (Lazara) da bacia Araguaia-das Mortes, M. formosa Costa & Brasil da varzea do medio rio Tocantins e M. splendida sp. nov. da varzea do rio Canabrava, bacia do rio Tocantins.
