Taxonomic review of Colombian Parodon (Characiformes: Parodontidae), with descriptions of three new species

Abstract

We review species of Parodon Valenciennes, 1850 from the Magdalena, Cauca, Orinoco, Amazonas, Atrato and Caribbean-Guajira River basins of Colombia using meristic and morphological characters. We recognize eight valid species, five previouslydescribed: P. apolinari Myers, from the Orinoco River basin; P. buckleyi Boulenger and P. pongoensis (Allen) from the upperAmazon; P. caliensis Boulenger, from the upper Cauca River drainage; and P. suborbitalis Valenciennes, from Lake Maracaibobasin. Three new species are described: P. alfonsoi, from the lower Magdalena River drainage; P. magdalenensis, from themiddle Magdalena and upper Cauca River drainages; and P. atratoensis, from the Atrato River basin. We redescribe Parodonsuborbitalis using type specimens and topotypes, and designate lectotypes. A taxonomic key is included for identification ofthe species, as well as geographic distribution maps. © 2011 Sociedade Brasileira de Ictiologia.
