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 CaribbeanGuajira River basins of Colombia using meristic and morphological characters. We recognize eight valid species, five previously described: P. apolinari Myers, from the Orinoco River basin; P. buckleyi Boulenger and P. pongoensis (Allen) from the upper Amazon; P. caliensis Boulenger, from the upper Cauca River drainage; and P. suborbitalis Valenciennes, from Lake Maracaibo basin. Three new species are described: P. alfonsoi, from the lower Magdalena River drainage; P. magdalenensis, from the middle Magdalena and upper Cauca River drainages; and P. atratoensis, from the Atrato River basin. We redescribe Parodon suborbitalis using type specimens and topotypes, and designate lectotypes. A taxonomic key is included for identification of the species, as well as geographic distribution maps.Espécies de Parodon Valenciennes, 1850 provenientes das bacias dos rios Magdalena, Cauca, Orinoco, Amazonas, Atrato e Caribe-Guajira da Colômbia são revisadas com base em caracteres merísticos e morfológicos. Oito espécies são consideradas válidas, sendo cinco previamente descritas: P. apolinari Myers, da bacia do rio Orinoco, P. buckleyi Boulenger e P. pongoensis (Allen) do alto rio Amazonas, P. caliensis Boulenger do alto rio Cauca e P. suborbitalis Valenciennes da bacia do lago Maracaibo. Três novas espécies são descritas: P. alfonsoi, do baixo rio Magdalena; P. magdalenensis, do médio rio Magdalena e da bacia superior do rio Cauca e P. atratoensis, da bacia do rio Atrato. Parodon suborbitalis é redescrita a partir de espécimes-tipo e topótipos. Designam-se lectótipos de P. suborbitalis. Uma chave para identificação das espécies é incluída, bem como mapas de distribuição geográfica.

Parodon orinocensis (Bonilla et al., 1999) (Characiformes: Parodontidae): emendations and generic reallocation

“…Standard length (SL) is presented after catalog numbers of the lots. All species from the family were examined except the recently described P. alfonsoi Londoño-Burbano, Román-Valencia & Taphorn, 2011, P. atratoensis Londoño-Burbano, Román-Valencia & Taphorn, 2011and P. magdalenensis Londoño-Burbano, Román-Valencia & Taphorn, 2011. Data from these three species were obtained exclusively from the original descriptions.…”

Estado de conservación y distribución de la biodiversidad de agua dulce en los Andes tropicales

“…Geographic range his species is only known from the Tucuy River in the Lower Magdalena River drainage, a tributary to the Río Calenturitas (9°37'N, 73°17'W), in the Municipality of La Jagua de Ibirico, Cesar, Colombia, at an elevation of 117 meters (Londoño-Burbano et al 2011). Its EOO is estimated at 2,860 km² (calculated as the minimum convex polygon around the sub-catchments where the species occurs) and it occurs in only one location, based on the main threat to the species (sedimentation and turbidity from deforestation).…”
