Helicoidea is a taxonomic superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora.


2005 taxonomy[edit]

There are 19 families within the superfamily Helicoidea according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005.[1][2]

According to H. Nordsieck[3] the family Xanthonychidae (sensu Hausdorf & Bouchet) is probably polyphyletic (contains several different lineages) and therefore should be divided into several families.

2012 taxonomy[edit]

Thompson & Naranjo-García (2012) described a new family Echinichidae and placed it to the superfamily Xanthonychoidea.[4] Therefore, the family Xanthonychidae was moved from Helicoidea to Xanthonychoidea.
