Pre-2008 taxonomy
editAccording 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. The family Cerionidae has no subfamilies.[4]
2008 taxonomy
editUit de Weerd (2008)[3] moved the Cerionidae to the newly established superfamily Urocoptoidea based on molecular phylogeny research.[3]
Fossil record
editThe 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.[6]
Genera
editGenera within the Cerionidae include:
- †Brasilennea Maury, 1935[7]
- Cerion Röding, 1798 - the type genus of the family Cerionidae[4]
- Mexistrophia Thompson, 2011[8]
