Abstract

New genera and species of radiolarians of the family Tetrentactiniidae Kozur et Mostler, 1979, rev. et emend. Afanasieva et Gainullina, 2025 are studied from the Lower Carboniferous (Mississippian) deposits of the Volga-Ural Basin and the Lower Permian (Cisuralian) sections of the South Urals. Two new genera, Longibelona gen. nov. and Tetraedrella gen. nov., are established, and five new species of radiolarians are described: Longibelona globosa sp. nov., L. alia sp. nov., L. neglecta sp. nov., Tetraedrella tetraedros sp. nov., Uralitina brevispina sp. nov. An extended description of the genus Uralitina and the species U. megalospina Afanasieva et Gainullina, 2025 is provided.
