<p>The present study describes three new species and two new genera of lungfish from the Upper Jurassic (Tithonian) of the Aliança Formation (Jatobá Basin), in the state of Pernambuco, northeastern Brazil. The new taxa, <i>Ceratodus ibimiriensis</i> sp. nov., <i>Tekoaceratodus pernambucensis</i> gen. et sp. nov., and <i>Asperideceratodus marisae</i> gen. et sp. nov<i>.,</i> are described from their tooth plates, and are attributed to the family Ceratodontidae. The morphological characteristics of these taxa are discussed, and a new phylogeny is proposed, together with ontogenetic and paleoecological considerations. The species are also compared with others from Gondwana, and a taxon proposed previously is revised. The present study expands existing knowledge on the lungfishes that inhabited the great lakes of the western extreme of Gondwana during the Jurassic.</p> <p><a target="_blank" href="http://zoobank.org/urna:lsid:zoobank.org:pub:B7818F16-1182-425C- A5F1-8268E6ACCE66">http://zoobank.org/urna:lsid:zoobank.org:pub:B7818F16-1182-425C- A5F1-8268E6ACCE66</a></p>
