As late as 1988, Diademodon had been considered a gomphodont due to its transversely expanded cheek teeth, however, it has since been placed in the order Cynodontia due to significant differences in skull morphology. Additional species were named by paleontologist A. S. Brink in 1979, although they are now considered synonyms of the type species Diademodon tetragonus. Fossils of the Diademodon tetragonus have more recently been found in the Omingonde Formation of Namibia, the Fremouw Formation of Antarctica, the Ntawere Formation of Zambia and the Río Seco de la Quebrada Formation in Mendoza Province, Argentina.
