Elphidae is a clade of bidentalian dicynodonts containing Elph, Katumbia, and Interpresosaurus.[1][2] It is exclusively known from the Late Permian of Russia and Tanzania. Elphidae is variously recovered as either at the base of a paraphyletic Cryptodontia,[2] or as basal dicynodontoids.[3]
The clade Elphinae was erected by Kurkin (2010) to pertain to a clade containing Elph and Interpresosaurus, two dicynodonts from Late Permian Russia. This clade was diagnosed by a sharply shortened preorbital skull, relatively small tusks located below the anterior orbit, and maxillae with depressions located below the naris.[4] Elphinae is often recovered forming a clade with the Tanzanian Katumbia,[1] to which the name Elphidae can be applied under the rules of the ICZN.[2]
