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




Taxonomy

The Bouchet et al. 2017 nomenclator provides an up to date system of Helicoidea. The system is in some parts preliminary, as the authors relied on unpublished (as of 2023) phylogenomic study, which did not include all New World taxa. They classified Epiphragmophoridae, Helminthoglyptidae, Humboldtianidae, Monadeniidae and Xanthonychidae (provisionally also Lysinoidae and Echinichidae) as subfamilies of the last taxon, because there are no deep splits between them in the cited unpublished study (see also Koene & Schulenburg 2005).
Cepolidae, Labyrinthidae and Thysanophoridae constitute the sister group of the remaining Helicoidea.

Cepolidae Ihering, 1909
Labyrinthidae Borrero, Sei, Robinson & Rosenberg, 2017
Thysanophoridae Pilsbry, 1926
Camaenidae Pilsbry, 1895
Polygyridae Pilsbry, 1895
Helicidae Rafinesque, 1815
Elonidae Gittenberger, 1977
Trissexodontidae H. Nordsieck, 1987
Helicodontidae Kobelt, 1904
Sphincterochilidae Zilch, 1960
Geomitridae C. Boettger, 1909
Canariellidae Schileyko, 1991
Hygromiidae Tryon, 1866
Pleurodontidae Ihering, 1912
Trichodiscinidae H. Nordsieck, 1987
Xanthonychidae Strebel & Pfeffer, 1879
Echinichinae F. G. Thompson & Naranjo-Garcia, 2012
Lysinoinae Hoffmann, 1928
Monadeniinae H. Nordsieck, 1987
Humboldtianinae Pilsbry, 1939
Helminthoglyptinae Pilsbry, 1939
Epiphragmophorinae Hoffmann, 1928
Xanthonychinae Strebel & Pfeffer, 1879




= 2015 taxonomy

=
Razkin et al. (2015) 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:

Bradybaeninae, subfamily of Camaenidae
Camaenidae
Canariellidae
Elonidae
Geomitridae
Geomitrinae
Cochlicellini
Geomitrini
Plentuisini
Ponentinini
Helicellinae
Cernuellini
Helicellini
Trochoideini
Helicodontidae
Helicidae
Ariantinae
Helicinae
Allognathini
Helicini
Otalini
Thebini
Murellinae
Humboldtianidae
Hygromiidae
Ciliellinae
Hygromiinae
Leptaxinae
Sphincterochilidae
Trissexodontidae
Gittenbergeriinae
Trissexodontinae




= 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.




= 2005 taxonomy

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

Helicidae
Bradybaenidae
Camaenidae
Cepolidae
Cochlicellidae
Elonidae
Epiphragmophoridae
Halolimnohelicidae
Helicodontidae
Helminthoglyptidae
Humboldtianidae
Hygromiidae
Monadeniidae
Pleurodontidae
Polygyridae
Sphincterochilidae
Thysanophoridae
Trissexodontidae
Xanthonychidae
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.
