Platynematichthys notatus is a species of catfish (order Siluriformes) of the monotypic genus Platynematichthys of the family Pimelodidae.^[1] This species reaches about 80 centimetres (31 in) SL and originates from 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]
