Helicoidei

Labyrinthus furcillatus, copyright Naturalis Biodiversity Center.

Belongs within: Heterobranchia.
Contains: Sagdidae, Thysanophoridae, Trissexodontidae, Sphincterochilidae, Pleurodontidae, Helicodontidae, Geomitrinae, Helicellinae, Triodopsinae, Polygyrinae, Epiphragmophora, Lysinoinae, Helminthoglyptinae, Humboldtiana, Leptaxinae, Trochulinae, Helicinae, Ariantinae, Amplirhagada, Austrochloritis, Sphaerospira, Figuladra, Torresitrachia, Steorra, Setobaudinia, Camaeninae, Bradybaeninae, Hadrinae.

The Helicoidei are a clade of terrestrial gastropods united by molecular phylogenetic analysis (Bouchet et al. 2017). Molecular data also support the division of the clade between two major subgroups, the less speciose Sagdoidea and the more diverse Helicoidea. The Sagdoidea are a strictly Neotropical group, with the highest diversity around the Caribbean basin, whereas Helicoidea are cosmopolitan. Members of the Helicoidea are also characterised by a thickened peristome, and the majority of families (except Sphincterochilidae and Cepolis) possess an odontognath (ribbed or striated) jaw. Many helicoids have a dart apparatus on the genitalia, but this is absent in many Camaenidae.
