Crenuchinae
The Crenuchidae, or crenuchids, are a family of freshwater fish of the order Characiformes. The 11 genera include about 115 species, though several species are undescribed. These fish are relatively small (usually under in standard length) and originate from eastern Panama and South America. Both subfamilies were previously included in the family Characidae, and were placed in a separate family by Buckup, 1998. Buckup, 1993, revised all genera, except ''Characidium''.Buckup, P.A. 1993. Review of the characidiin fishes (Teleostei: Characiformes), with descriptions of four new genera and ten new species. Ichthyological Exploration of Freshwaters 4(2):97-154. They are the only members of the superfamily Crenuchoidea. They are the most basal members of the suborder Characoidei, and diverged during the Early Cretaceous, prior to the split between the African characins (Alestoidea) and the other South American characins (Erythrinoidea and Characoidea). This suggests that their dive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crenuchus
The sailfin tetra (''Crenuchus spilurus''), also known as the mojarita, is a species belonging to the South American darter family, Crenuchidae. It is found in the Amazon and Orinoco Basins, as well as various river Basins in the Guianas. It is the only member of the monospecific genus, ''Crenuchus'', one of two genera within the subfamily Crenuchinae. Taxonomy The sailfin tetra was first formally described in 1863 by the German-born British ichthyologist Albert Günther with its type locality given as the Essequibo River in Guyana. When he described this species, Günther proposed the new monospecific genus ''Crenuchus''. This taxon is classified within the subfamily Crenuchinae of the family Crenuchidae in the suborder Characoidei of the order Characiformes, the characins and related fishes. Etymology The sailfin tetra is the only species in the genus ''Crenuchus'', this name is a combination of ''crena'', a Latin word meaning "notch", and ''nucha'', Medieval Latin for the na ...
