Platynematichthys notatus is a species of catfish (order Siluriformes) of the monotypic genus Platynematichthys of the family Pimelodidae.[1] This species reaches 80.0 centimetres (31.5 in) SL. This species is native to the Amazon and Orinoco River basins.[2]
Platynematichthys and its sister group Brachyplatystoma are the only genera in the tribe Brachyplatystomatini. These two genera are characterized by two synapomorphies; these include a gas bladder divided into an anterior portion and a triangular posterior portion, as well as a ventral crest under the cleithrum, the main bone supporting the pectoral fins.[3]
