Cynodon, is a genus of freshwater ray-finned fishes belonging to the family Cynodontidae, the dogtooth characins. These piscivorous fishes are found in tropical South America.
Cynodon was first proposed as genus in 1829 by the French zoologist Georges Cuvier with its only species being Hydrocynus scomberoides, this name was also proposed by Johann Baptist von Spix in 1829 with Cynodon gibbus given as the only species. Cuviers's name is technically a senior synonym of Hydrolycus but the name was suppressed in the IUCN Opinion 2012.[1] Cynodon gibbus was first formally described as Raphiodon gibbus by Spix and Louis Agassiz in 1829 with its type locality given as Lago Manacapuru in the Amazonas State, Brazil. However, in the plate preceding the description in Selecta genera et species piscium : quos in itinere per Brasiliam annis MDCCCXVII-MDCCCXX jussu et auspiciis Maximiliani Josephi I it was named as Cynodon gibbus and the IUCN Opinion 2012 confirmed that this was the valid name for this taxon.[2] This taxon is the type genus of the family Cynodontidae which was named by Carl H. Eigenmann in 1903.[3] This family Cynodontidae belongs to the suborder Characoidei of the order Characiformes.[4]
