Taxonomy
editThe genus was erected by Berg in 1940. In 1974, Sergienko described a new genus and species Heterolepis multa from the Middle Permian (Kazanian) of Kemerovo Region, Russia, as a new member of the Palaeoniscidae family. However, Heterolepis was already in use for the extant snake Heterolepis capensis (Smith, 1847), making Sergienko's naming a junior homonym. In 2023, A. S. Bakaev redescribed "Heterolepis" multa as a new species in the genus Eurynotoides, E. multa. This species is different from E. nanus and E. costatus by having ganoin peninsula-shaped structures on the anterior margin of the scale as well as by the presence of denticles on both posterior and lower edge of the scale.[2]
