Popis: The genera of the Brasilodontidae, Protheriodon, Brasilodon, Brasilitherium, Minicynodon and the Indian Panchetocynodon, are briefly summarised and the more significant evolutionary information from them is discussed. Brasilodon and Brasilitherium are possibly related to the origin of Kuehneotheridae and Morganucodontidae, respectively. A systematic rearrangement is proposed for the monophyletic Epicynodontia integrated by the subclades Brasilodontia, Gomphodontia and Galesauria. It is considered that Brasilodontia (Brasilodontidae and Tritheledontidae) have strong differences with the remaining cynodonts and are connected with the origin of mammals. It is recognised that Galesauridae, Thrinaxodontidae and Probainognathidae are only distantly related to the origin of mammals. Within the Brasilodontidae were not found any dental or mandibular character shared with the Haramiyavidae.
