In this short paper two new cyrtoneritimorph gastropod genera are described from the Late Silurian of Bohemia and Middle Devonian of Germany. The oldest known cyrtoneritimorph genus, Krameriella gen. nov., is placed within a new subfamily, Krameriellinae subfam. nov., of the Vltaviellidae. Ordovician-Permian Cyrtoneritimorpha are considered to be a gastropod group of uncertain systematic position. New taxa: Krameriella hornyi gen. et sp. nov., and Eifelcyrtus blodgetti gen. et sp. nov.
