Geomitridae is a taxonomic family of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
Anatomy The family is characterized by the presence of a free right ommatophoral retractor (passing outside the peni-oviducal angle) and a double stimulatory apparatus. A free right ommatophoral retractor has been linked to adaptation to xeric habitats.
Taxonomy The family Geomitridae is subdivided in the following subfamilies (according to Razkin et al., 2015). Genera with the family Geomitridae include:
