Platynematichthys notatus, the lince catfish, is a species of catfish (order Siluriformes) of the monotypic genus Platynematichthys of the family Pimelodidae. It is native to the Amazon and Orinoco basins in South America. In the Orinoco this distinctly spotted species reaches up to 1 m (3.3 ft) in standard length, but it reportedly only reaches about half that size in the Amazon.
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.
