The protoconch and teleoconch morphology of the Late Badenian and Sarmatian species of the genus Mohrensternia of the Central Paratethys are described and illustrated.

M. friedbergi sp. nov. A lectotype is designated for Rissoa angulata EICHWALD, 1830, the type species of Mohrensternia STOLICZKA, 1868. The type material of all species introduced by W.
