- Pareiasaurs were an enigmatic and diverse group of parareptilian herbivores of the middle and late Permian. Nanoparia luckhoffi was erected in 1936 but remains the least well-known member of four “dwarf” pareiasaurs that comprise Pumiliopareiasauria. After new preparation of the holotype, we present the first detailed cranial description of Nanoparia luckhoffi and a new diagnosis for the taxon based on seven autapomorphies: (1) an additional bone on the posterior margin of the cheek flange between the squamosal and quadratojugal; (2) a pyramidal-shaped parietal; (3) a very short, square lacrimal; (4) paired prepalatal foramina positioned anterolaterally on the internalpremaxillary palatal flange; (5) notch on anteromedial border of the choana; (6) a ventral flange formed by the lateral margin of the internal tabulars; and (7) tabulars that extend posteriorly further than the supratemporals. We find evidence supporting a juvenile ontogenetic state for the holotype, including small skull; unossified open cranial sutures; an unossified dorsal braincase; and fewer marginal teeth than most pareiasaurs. An updated phylogeny recovers Nanoparia as a sister taxon to Provelosaurus americanus from Brazil and remains a constituent member of Pumiliopareiasauria.
Os pareiassauros foram um enigmático e diverso grupo de pararrépteis herbívoros do Permiano médio e inferior. Nanoparia luckhoffi foi proposta em 1936, mas é um dos menos conhecidos pareiassauros “anões” que formam os Pumiliopareiasauria. Após nova preparação do holótipo, apresentamos a primeira descrição detalhada de Nanoparia luckhoffi e uma nova diagnose para o táxon, baseado em sete autapomorfias: (1) um osso adicional na margem posterior da aba temporal entre o esquamosal e o quadradojugal; (2) parietal com formato piramidal; (3) lacrimal muito curto e com formato quadrado; (4) forame prepalatal posicionado anterolateralmente na vista interna da pré-maxila; (5) entalhe na borda anteromedial da coana; (6) aba ventral ao longo da margem lateral na vista interna dos tabulares; e (7) tabulares estendendo-se posteriormente mais do que os supratemporais. Encontramos evidência que apoia um estágio juvenil no holótipo, incluindo crânio pequeno, suturas cranianas abertas, não-ossificadas; neurocrânio não-ossificado; e menos dentes marginais do que a maioria dos pareiassauros. Uma filogenia atualizada mostra a Nanoparia como o táxon irmão de Provelosaurus americanus do Brasil, continuando como membro dos Pumiliopareiasauria.
