This dataset contains the digitized treatments in Plazi based on the original journal article Giovannetti, Victor, Toledo-Piza, Mônica, Menezes, Naércio A. (2017): Taxonomic revision of Galeocharax (Characiformes: Characidae: Characinae). Neotropical Ichthyology 15 (1): e 160040, DOI: 10.1590/1982-0224-20160040, URL: dx.doi.org/10.1590/1982-0224-20160040 The taxonomy of Galeocharax, a genus of freshwater fishes distributed in most South American cis-Andean river systems, except the rio Negro, rio São Francisco and rio Xingu basins and the eastern drainages of Brazil, is herein revised.

A total of 1229 specimens were examined from which 680 had meristic and morphometric data taken. Osteological and morphological features were also examined through radiographs, scanning electron microscopy and in cleared and stained specimens. Three of the four species previously considered as valid are herein recognized: Galeocharax humeralis from rio Paraguay and lower rio Paraná basins; Galeocharax goeldii, from rio Madeira basin, with records of geographical distribution expanded to the río Madre de Dios, río Beni, rio Mamoré and rio Guaporé basins and Galeocharax gulo, which is widespread throughout rio Amazonas, río Orinoco, rio Tocantins, and upper rio Paraná basins.
