Nycteroleter is an extinct genus of nycteroleterid parareptile known from the Middle Permian of European Russia. Fossils were first found in the Mezen River, near to Arkhangelsk. Within the Nycteroleteridae, it is considered most closely related to Emeroleter. However, its legs were shorter than those of Emeroleter and its skull was flatter. Nycteroleter was insectivorous, and may have been nocturnal. It was a small animal, less than a metre long.
Sclerosaurus is an extinct genus of procolophonid parareptile known from the Early to Middle Triassic of Germany and Switzerland. It contains a single species, Sclerosaurus armatus. It was fairly small about 30 cm long, distinguished from other known parareptiles by the possession of long, backwardly projecting spikes, rear lower jaw teeth with slightly imbricating crowns, and a narrow band of back armor comprising two or three rows of sculptured osteoderms on either side of the midline.
Phonodus is an extinct genus of procolophonid parareptile. It is known from a single skull found from the Early Triassic Katberg Formation in South Africa. It is the oldest known member of the subfamily Leptopleuroninae, and was likely the result of a procolophonid migration into the Karoo Basin from Laurasia after the Permo-Triassic extinction event. Because Phonodus had large maxillary teeth underneath a large antorbital buttress, and a lack of ventral temporal emargination along the side of the skull, it probably had a durophagous diet.
Soturnia is an extinct genus of procolophonid parareptile. It is known from rocks of the Late Triassic-age Caturrita Formation of the municipality of Faxinal do Soturno in the geopark of Paleorrota, Brazil. Soturnia was named in 2003 by Cisneros and Schultz; the type species is S. caliodon. It was a leptopleuroninae procolophonid.
Pintosaurus is an extinct genus of basal procolophonid parareptile from Late Triassic deposits of northeastern Uruguay. It is known from the holotype FC-DPV 1181, a partial skull. It was collected from the Buena Vista Formation of the Paraná Basin, in Colonia Orozco, Cerro Largo Department. It was first named by Graciela Piñeiro, Alejandra Rojas and Martín Ubilla in 2004 and the type species is Pintosaurus magnidentis. The specific name means "large dentary" in Greek.
Theledectes is an extinct genus of theledectine procolophonid parareptile from middle Triassic deposits of Free State Province, South Africa.The type species, Theledectes perforatus, is based on the holotype BP/1/4585, a flattened skull. This skull was collected by the South African palaeontologist, James W. Kitching from Hugoskop in the Rouxville District and referred to subzone B of the Cynognathus Assemblage Zone of the Burgersdorp Formation, Beaufort Group. The genus was first named by Sean P. Modesto and Ross J. Damiani in 2003. However, the species was initially assigned to the genus Thelegnathus by C.E. Gow in 1977, as the species Thelegnathus perforatus.
Theledectinae is an extinct subfamily of parareptiles within the family Procolophonidae. Theledectines existed in South Africa, China and Australia during the Early-Middle Triassic period. Theledectinae was named by Juan Carlos Cisneros in 2008 to include the genus Theledectes, and the species "Eumetabolodon" dongshengensis. "E." dongshengensis represents a new genus from China. Cladistically, it is defined as "All taxa more closely related to Theledectes perforatus than to Procolophon trigoniceps Owen, 1876". In 2020, Hamley add the new genus Eomurruna from Australia to this subfamily

Eumetabolodon is an extinct genus of procolophonine procolophonid parareptile from early and middle Triassic deposits of Nei Mongol, northern China. Two species of Eumetabolodon were named by J. L. Li in 1983 and the type species is Eumetabolodon bathycephalus.
Anomoiodon is an extinct genus of procolophonine procolophonid parareptile from early Triassic deposits of Thuringia, Germany. It is known only from the holotype MB.R.3539B and paratype MB.R.3539A, two articulated, three-dimensionally preserved partial skeletons on one block which represent two individuals. The holotype includes nearly complete skull and lower jaw. The block was collected from the lowest layer of the Chirotherium Sandstone Member of the Solling Formation, dating to the early Olenekian faunal stage of the Early Triassic, about 249-247 million years ago. It was first named by Friedrich von Huene in 1939 and the type species is Anomoiodon liliensterni. Laura K. Säilä, who redescribed Anomoiodon in 2008, found it to be a leptopleuronine using a phylogenetic analysis. The most recent analysis, performed by Ruta et al. (2011) found it to be a procolophonine instead. However, both analyses found that it is most closely related to the Russian procolophonid Kapes.
Procolophoninae is an extinct subfamily of procolophonid parareptiles from the late Early Triassic to the early Middle Triassic of Africa, Antarctica, Asia, Europe and South America. Currently, the oldest-known procolophonine is Procolophon from the earliest Olenekian stage.
Leptopleuroninae is an extinct subfamily of procolophonid reptiles.
Pentaedrusaurus is an extinct genus of procolophonid parareptile from the Early Triassic of China. It is one of the most basal members of the procolophonid subfamily Leptopleuroninae. The only known species of Pentaedrusaurus, P. ordosianus, was named in 1989 from the Heshanggou Formation.
Scoloparia is an extinct genus of procolophonid parareptile from the Triassic of Canada. Fossils have been found in the Early Triassic to Norian-age Wolfville Formation in Nova Scotia, Canada.
Kapes is an extinct genus of procolophonid parareptile from the Lower and Middle Triassic of the United Kingdom and Russia. It is a member of the subfamily Procolophoninae. The type species K. amaenus was named in 1975 from the banks of the Vychegda River in the Komi Republic of Russia. In 1983, a new species was brought into the genus, K. majmesculae. K. majmesculae was first named in 1968 as a member of the genus Tichvinskia. A third Russian species, K. serotinus, was named in 1991. In 2002, Kapes bentoni was named from the Middle Triassic Otter Sandstone Formation of Devon, England, extending the geographic range of Kapes. In the same paper, K. serotinus was synonymized with K. majmesculae and another Russian species was assigned to Kapes called K. komiensis. K. komiensis was first named in 1975 as a member of the genus Macrophon.
Koiloskiosaurus is an extinct genus of procolophonid parareptile from the Early Triassic of Germany. The type and only species Koiloskiosaurus coburgensis was named by German paleontologist Friedrich von Huene in 1911 from a layer of rocks called the Buntsandstein. Koiloskiosaurus coburgensis is known from a block of three fossilized skeletons preserved together. Given that the skeletons are oriented in the same direction, the individuals most likely died in a burrow. Features of the skeletons of Koiloskiosaurus and other procolophonids, such as robust limbs and solid, immovable skull bones, are also taken as evidence that they were burrowers.
Coelodontognathus is an extinct genus of reptile from the Early Triassic of European Russia. It was originally described as a procolophonid parareptile in 1967 but was reclassified as a possible trilophosaurid archosauromorph in 2008. The genus includes two species: the type species C. donensis and C. ricovi. C. donensis is known from the holotype PIN 4173/129 and the referred PIN 4173/130, and C. ricovi is known from the holotype PIN 4173/127 and the referred PIN 4173/128, all of which represent dentaries that are housed at the Paleontological Institute, Russian Academy of Sciences. Another dentary, SGU 104/3105, originally referred to C. donensis was reassigned to its own genus and species Vitalia grata by Ivakhnenko, 1973. The fossils have been found at the Donskaya Luka Locality near the village of Sirotinskaya and the Don River in Ilovlinsky District, Volgograd Oblast, from the Lipovskaya Formation of the Gamskii Horizon. Like Coelodontognathus, Vitalia which is known from the same locality was also first identified as a procolophonid and later reclassified as a trilophosaurid. Coelodontognathus and Vitalia are similar to procolophonids in that they have wide teeth but differs from them in that they have tooth roots set deep into the jaws.
