Taxonomy

2005 taxonomy

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

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.

2015 taxonomy

Razkin et al. (2015) [5] reorganized classification into monophyletic taxa according to the molecular phylogeny. This study is focus on Western Palaearctic species. The Hygromiidae s.l. family was divided into three families, Canariellidae, Geomitridae and Hygromiidae. Moreover, the family Cochlicellidae was including within the Geomitridae family as a tribe (Cochlicellini).

The classification proposed for Western Palaearctic Helicoidea is as follows:
