'''Chilodontaidae''' is a taxonomic family of mostly small deepwater sea snails, marine gastropod molluscs in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
== Taxonomy == The family was previously in the superfamily Neritoidea in the order Neritopsina and the superorder Neritaemorphi.
=== 2005 taxonomy === This family consists of three following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): *Chilodontainae <small>Wenz, 1938</small> *Calliotropinae <small>Hickman & McLean, 1990</small> *Cataeginae <small>McLean & Quinn, 1987</small>
=== 2007 taxonomy === A molecular phylogeny-based taxonomy of the Seguenzioidea was published by Kano (2007).<ref name="Kano 2007">Kano Y. (2007). "Vetigastropod phylogeny and a new concept of Seguenzioidea: independent evolution of copulatory organs in the deep-sea habitats". ''Zoologica Scripta'' '''37'''(1): 1–21. {{doi|10.1111/j.1463-6409.2007.00316.x}}</ref>
It was proposed to rename the family Chilodontidae <small>Wenz, 1938</small> as "Chilodontaidae" because it was a homonym of the fish family "Chilodontidae" <small>Eigenmann, 1912</small>, but a 2024 ICZN ruling instead changed the name of the fish family to Chilodidae, so the gastropod family is still to be kept as Chilodontidae.<ref>Opinion 2502 (Case 3555) – Chilodontidae Bronn, 1859 (Ciliophora), Chilodontinae Eigenmann, 1910 (Pisces, Characiformes) and Chilodontinae Wenz, 1938 (Mollusca, Gastropoda): homonymy between family-group names resolved. The Bulletin of Zoological Nomenclature 81(1): 133-136 (31 December 2024) doi:10.21805/bzn.v81.a025</ref>
The subfamilies Calliotropinae Hickman & McLean, 1990 and Cataeginae McLean & Quinn, 1987 were raised to family levels as the Calliotropidae and the Cataegidae.
