Abstract: The Itapecuru is a relatively large river in the northeastern Brazilian state of Maranhão. During several expeditions to this basin, we collected 69 fish species belonging to 65 genera, 29 families and 10 orders. Characiformes and Siluriformes were the orders with the largest number of species and Characidae, Loricariidae, Cichlidae, Auchenipteridae and Pimelodidae were the richest families. About 30% of the fish fauna of the Itapecuru basin is endemic or restricted to northeastern Brazil. Just over a fifth (2… Show more

“…However, some records of Charax for the coastal river basins of northeastern Brazil were made before the taxonomic revision made by Menezes and Lucena (2014): Martins and Oliveira (2011) recorded C. gibbosus for the Rio Mearim basin; Barros et al (2011) recorded Charax sp. for the Rio Itapecuru basin; Martins and Oliveira (2011) recorded Charax sp.…”

“…Two studies analyzing morphological evidence have focused on the diversity of fish in the Itapecuru River. In the first study (Piorski et al, 1998), 41 species belonging to 36 genera and 13 families were identified on the lower Itapecuru, while in the second, more comprehensive study (Barros et al, 2011), 69 species representing 65 genera, 29 families, and 10 orders, were identified in the three sectors of the basin.…”

“…In 1937, this valuable material was sent to the curator of fishes, Henry W. Fowler, at the Academy of Natural Sciences of Philadelphia (ANSP), who described 36 new species from the rio Parnaíba in Piauí State, rio São Francisco in Pernambuco State, rio Jaguaribe and other small coastal basins of Ceará, Rio Grande do Norte and Paraíba States (Fowler, 1941). However, that study, as others involving the freshwater fish fauna from northeastern Brazil, presents succinct descriptions, erroneous identification, and confused taxonomy, with some taxa probably being synonyms to species previously described (Rosa et al, 2003;Barros et al, 2011). Among those, is the original description of Plecostomus spilurus, based on six specimens collected in the rio Salgado, a tributary of the upper rio Jaguaribe basin, at Icó Municipality, Ceará State, with the holotype deposited under catalog number ANSP 69403 and five paratypes catalogued as ANSP 69404 to 69408.…”

“…Piorski (2010) inventorying the region of Pindaré and Alto Turiaçu sampled the Characiformes as the most representative, consisting of species with different habits. Barros et al (2011) in a survey in Itapecuru river basin were identified 69 species, 29 families, and 10 orders. Characiformes and Siluriformes were the richest orders with 24 and 25 species respectively.…”
