There are at least four known species: B. balatonicus, B. oyama, B. shoshonensis, and B. zitteli. The shell of Balatonites is essentially evolute, coiled with earlier whorls showing, and is laterally compressed with flattish sides and a roof-like venter. The sides are covered with radial ribs that have tubercles generally arranged in umbilical, median and ventral rows. Balatonites has been found in the Alps, Balkans, Germany, Japan, and Nevada.
