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

Families within the superfamily Helicoidea

Helicoidea consist of 19 families according to Bouchet & Rocroi (2005). [Bouchet, P.; Rocroi, J.-P. (Ed.); Frýda,J.; Hausdorf,B.; Ponder, W.; Valdes, A.; Warén, A. (2005). Classification and nomenclator of gastropod families. Malacologia: International Journal of Malacology, 47(1-2). ConchBooks: Hackenheim, Germany. ISBN 3-925919-72-4. 397 pp. http://www.vliz.be/Vmdcdata/imis2/ref.php?refid=78278] [Poppe G.T. & Tagaro S.P. 2006. The new classification of Gastropods according to Bouchet & Rocroi, 2005.

According to H. Nordsieck [ [http://www.clausilia.de/media//DIR_64901/04_2006_helicoidea.pdf Higher classification of the Helicoidea and the molecular analyses of their phylogeny (by Hartmut Nordsieck)] ] the family "Xanthonychidae" (sensu Hausdorf & Bouchet) is probably a polyphyletic assemblage and should be divided into several families.
