Family Nycteroleteridae
Superfamily Pareiasauroidea
Pareiasauromorpha is a group of parareptilian amniotes from the Permian. It includes genera found all over the world, with many genera from Asia and South Africa. The clade was first used as a group by Linda A. Tsuji in 2011, in order to group the family Nycteroleteridae (nycteroleters) and the superfamily Pareiasauroidea (pareiasaurs). Pareiasauromorpha is considered to be a monophyletic node, the sister group to procolophonoids.
Pareiasauromorpha was first used to define a group of parareptilians in 2011 by Linda A. Tsuji. The next year, Tsuji and her colleagues used Pareiasauromorpha as a node inside Procolophonia. In their 2012 publication, Tsuji et al. defined it as a monophyletic node containing "nycteroleters" (the family Nycteroleteridae) and "pareiasaurs" (in the superfamily Pareiasauroidea).
Nycteroleteridae is a family, commonly called "nycteroleters", classified in Pareiasauromorpha. The group includes the genera Emeroleter, Nycteroleter, Bashykroleter, Rhipaeosaurus, Macroleter, and "Bashykroleter" mesensis. The genus Tokosaurus is often classified as the sister taxon to Macroleter, but is actually more likely a juvenile of the later. Bashykroleter, including both species, is now considered paraphyletic, as "B." mesensis is more closely related to other genera than the type species B. bashkyricus.
