It was reranked as the suborder Therocephalia by Osborn (1904), Gregory (1910), Nopcsa (1923), Kuhn (1946), Huene (1954), Kemp (1982) and Carroll (1988); it was reranked as the suborder Therocephali by Jaekel (1911); it was reranked as the infraorder Therocephalia by Haughton and Brink (1954), Olson (1966) and Battail and Surkov (2000); it was reranked as the unranked clade Therocephalia by Gauthier et al. (1989), Rubidge and Sidor (2001), Abdala et al. (2008) and Huttenlocker and Smith (2017).

It was assigned to Therapsidi by Jaekel (1911); to Theriodontia by Osborn (1904) and Nopcsa (1923); to Theromorpha by Kuhn (1946); to Theriodonta by Olson (1966); to Therosauria by Kemp (1982); to Therapsida by Gregory (1910), Huene (1954) and Carroll (1988); to Theriodontia by Haughton and Brink (1954) and Battail and Surkov (2000); to Eutheriodontia by Rubidge and Sidor (2001); to Eutherapsida by Ivakhnenko (2011); to Therapsida by Gauthier et al. (1989), Abdala et al. (2008) and Huttenlocker and Smith (2017); and to Therapsida by Broom (1913), Liu and Abdala (2019) and Liu and Abdala (2020).
