Kistecephalia
Kistecephalia is a clade of dicynodont therapsids. The group was first named in 1894, and was reinstated as a clade in 2009. Kistecephalia is a stem-based taxon defined as all taxa more closely related to '' Cistecephalus microrhinus'' than '' Emydops arctatus''. It includes the families Myosauridae, Kingoriidae, and Cistecephalidae and is part of the larger group Emydopoidea. Kistecephalians were small in comparison to other dicynodonts. One group of kistecephalians, the cistecephalids, are thought to have been burrowers. Below is a cladogram from Kammerer ''et al.''

Dicynodont
Dicynodontia is an extinct clade of anomodonts, an extinct type of non-mammalian therapsid. Dicynodonts were herbivorous animals with a pair of tusks, hence their name, which means 'two dog tooth'. Members of the group possessed a horny, typically toothless beak, unique amongst all synapsids. Dicynodonts first appeared in Southern Pangaea during the mid-Permian, ca. 270–260 million years ago, and became globally distributed and the dominant herbivorous animals in the Late Permian, ca. 260–252 Mya. They were devastated by the end-Permian Extinction that wiped out most other therapsids ca. 252 Mya. They rebounded during the Triassic but died out towards the end of that period. They were the most successful and diverse of the non-mammalian therapsids, with over 70 genera known, varying from rat-sized burrowers to elephant-sized browsers. Characteristics The dicynodont skull is highly specialised, light but strong, with the synapsid temporal openings at the rear of the skull ...

Emydopoidea
Emydopoidea is a group of Late Permian dicynodont therapsids. It includes the small-bodied ''Emydops'', ''Myosaurus'', and kingoriids, and the burrowing cistecephalids.

Dicynodontoides Recurvidens
''Dicynodontoides'' is a genus of small to medium-bodied, herbivorous, emydopoid dicynodonts from the Late Permian. The name ''Dicynodontoides'' references its “dicynodont-like” appearance (dicynodont = two-dog-tooth) due to the caniniform tusks featured by most members of this infraorder. ''Kingoria'', a junior synonym, has been used more widely in the literature than the more obscure ''Dicynodontoides'', which is similar-sounding to another distantly related genus of dicynodont, ''Dicynodon''. Two species are recognized: ''D. recurvidens'' from South Africa, and ''D. nowacki'' from Tanzania.Angielczyk K.D., Sidor C.A., Nesbitt S.J., Smith R.M.H & Tsuji L.A. 2009.

Cistecephalus
''Cistecephalus'' is an extinct genus of dicynodont therapsid from the Late Permian of southern Africa (South Africa and Zambia). It was a small, specialised, burrowing dicynodont, possibly with habits similar to a modern mole. The head was flattened and wedge-shaped, the body long, and the forelimbs very strong, with similarities in structure to the forelimb of modern burrowing mammals. It was one of the first genera of dicynodonts to be described, by Richard Owen, in 1876. ''Cistecephalus'' could reach up to in length. Description ''Cistecephalus'' was one of the most atypical dicynodont genera. However, it was broadly similar in anatomy to other cistecephalids, all of which share similar adaptations to digging. Its skull was broad, with laterally-directed temporal openings and a sharply tapering snout, similar to extant fossorial animals. However, it has relatively large, anteriorly-directed orbits, suggesting binocular vision. It had a short neck and laterally-directed sho ...

Eosimops
''Eosimops'' is an extinct genus of pylaecephalid dicynodonts. They were small synapsids superficially resembling modern mammals. ''Eosimops'' is known from several skull specimens, as well as one complete skeleton. ''Eosimops'' lived during the Middle Permian of South Africa. Etymology ''Eosimops'' was named in by South African paleontologist Robert Broom. Its name is derived from the Ancient Greek ''Ēṓs'' (“dawn”) and ''ópsis'' (“appearance”). Discovery ''Eosimops'' was discovered in 1921 by Robert Broom, based on a single skull. It was found in the ''Tapinocephalus'' Assemblage Zone strata of South Africa, an area which provides a rich variety of early therapsids and covers a period of almost 100 million years ranging from the Permian to the Jurassic. Later, other skull specimens as well as a complete skeleton were found. ''Eosimops'' is found above the stratigraphic range of the early dicynodont '' Eodycynodon''.

Robertia
''Robertia'' is an extinct genus of small herbivorous dicynodonts from the Middle to Late Permian of South Africa, between 260 and 265 million years ago. It is a monospecific genus, consisting of the type-species ''R. broomiana,'' which was classified by Lieuwe Dirk Boonstra in 1948 and named in honor of Robert Broom for his study of South African mammal-like reptiles. ''Robertia'' had characteristic caniniform tusks and few, small teeth on the maxillary and dentary table. Its beak and the propalinal movement of the jaw, as with other dicynodonts, allowed for efficient cutting of plant matter. The solid, barrel-bodied creatures had a sprawling stance with a flexible backbone, which likely gave them a lizard-like appearance as they moved.King, G. (1981).

Myosaurus
''Myosaurus'' is an extinct genus of dicynodont found primarily in Antarctica and South Africa. History The family Myosauridae is known only from fossilized skull specimens. The family is distinguished from other families in the infraorder Dicynodontia by the larger breadth of the skull samples in the intertemporal region. ''Myosaurus'' used to be a member of the family Endothiodontidae but was placed in its own family after further investigation.
