Cyclophoroidea is a superfamily of land snails with an operculum, terrestrial gastropods within the order Architaenioglossa, that belongs to the subclass Caenogastropoda.Bouchet, P.; Rosenberg, G.; Gofas, S. (2015). Cyclophoroidea Gray, 1847. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=153654 on 2015-02-16 Approximately 3,675 cyclophoroid species were known as of 2024, making them the second-most diverse clade of land snails after Stylommatophora.
These terrestrial gastropods have lost the ctenidium (comb-like respiratory apparatus) and osphradium, and the pallial cavity has been modified as a lung.
Cyclophoroids have detritivorous or herbivorous diets.
Cyclophoroids probably originated in the Late Jurassic or Early Cretaceous based on molecular clock estimates. Several fossil species are known from Burmese amber that dates to the mid-Cretaceous, approximately 99 million years ago.
