Abstract

Permian ray-finned fishes from freshwater deposits of the Leninsk (Tatarian Series, Severodvinian Stage) and the Tailugan Formations (Tatarian Series, Vyatkian Stage) of Kuznetsk Basin are revised. The taxa considered in the work were not previously formally published and remained nomina nuda. Two new genera (Gregarialepis and Planalepis) and two new species (G. binaria and P. diserta) are described. Scales of Heterolepis undata (reidentified cf. Eurynotoides sp.), Mitinolepis surickovensis (reidentified Strelnia sp.), are too poorly preserved, the available features are not sufficient to distinguish new taxa, and they can only be identified to genus-level.
