2005 taxonomy
There are 19 families within the superfamily Helicoidea according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005.
According to H. Nordsieck the family Xanthonychidae (sensu Hausdorf & Bouchet) is probably polyphyletic (contains several different lineages) and therefore should be divided into several families.
2012 taxonomy
Thompson & Naranjo-García (2012) described a new family Echinichidae and placed it to the superfamily Xanthonychoidea. Therefore, the family Xanthonychidae was moved from Helicoidea to Xanthonychoidea.
2015 taxonomy
Razkin et al. (2015) reorganized classification into monophyletic taxa according to the molecular phylogeny.
