"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.cite journal|url=http://www.bioone.org/archive/0045-8511/2005/3/pdf/i0045-8511-2005-3-492.pdf|title="Brachyplatystoma capapretum": a New Species of Goliath Catfish from the Amazon Basin, with a Reclassification of Allied Catfishes (Siluriformes: Pimelodidae)|journal=Copeia|format=PDF|year=2005|pages=492–516|issue=3|last=Lundberg|first=John G.|coauthors=Akama, Alberto|doi=10.1643/CI-04-036R1|volume=2005]
