Alycaeinae Cyclophorinae Spirostomatinae Alycaeidae Blanford, 1864 Cyclophoridae is a taxonomic family of small to large tropical land snails with an operculum, terrestrial gastropod mollusks in the order Architaenioglossa belonging to the subclass Caenogastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

This diverse family with many species is now limited to the representatives in the tropics and subtropics of the Old and New World.

Their fossil history dates back through the Early Tertiary[1] to the Cenomanian age of the Cretaceous.

[2] The dextral shells are mostly of small and rarely medium size.

This family consists of the following subfamilies according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, which adapted the tribes of Cyclophorinae from the system used by Wenz (1938).
