The Eudimorphodontinae includes all taxa more closely related to ''Eudimorphodon ranzii'' than to '' Raeticodactylus filisurensis'' while the Raeticodactylinae includes all taxa more closely related to ''Raeticodactylus filisurensis'' than to ''Eudimorphodon ranzii''. More recently, ''Raeticodactylus'' and ''Caviramus'' were moved into their own family, Raeticodactylidae. The below cladogram follows that analysis. In 2020 however, a study upheld by Matthew G.
