Cyclophoroidea is a superfamily of land snails with an operculum, terrestrial gastropods within the order Architaenioglossa, that belongs to the subclass Caenogastropoda. [1] Approximately 3,675 cyclophoroid species were known as of 2024, making them the second-most diverse clade of land snails after Stylommatophora. [2]
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. [3]
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. [4]
According to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), this superfamily consists of the following families:
