Cerionidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Urocoptoidea.

[3] According to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005),[4] the family Cerionidae is classified in the superfamily Orthalicoidea, within the informal group Sigmurethra, itself belonging to the clade Stylommatophora within the clade Eupulmonata.

[4] Uit de Weerd (2008)[3] moved the Cerionidae to the newly established superfamily Urocoptoidea based on molecular phylogeny research.

[3] The oldest fossil cerionid is C. acherontis from the Upper Cretaceous Hell Creek Formation, in Montana, northwestern USA.

[5] The second oldest record is the genus Brasilennea from the Brazilian Paleocene Itaboraí Basin, in Rio de Janeiro.
