This paper addresses some issues about the taxonomy of two traversodontid cynodonts: Exaeretodon. and Ischignathus. The type species of Exaeretodon, a Late Triassic genus, is E. frenguellii, but the valid name of the Argentinian species is E. argentinus. Another species of this genus is E. riograndensis from Brazil. Part of the holotype of Traversodon major from Brazil, that was subsequently allocated in Exaeretodon, as well as Exaeretodon statisticae from India, are considered as indeterminate species of Exaeretodon. After a detailed discussion of the diagnoses of Ischignathus sudamericanus, this taxon is regarded as a junior synonym of Exaeretodon argentinus.
