Superfamily of gastropods
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]
