Camaenidae

Camaenidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea, the typical snails and their allies. This is one of the most diverse families in the clade Stylommatophora. These snails occur in a wide variety of habitats in the tropics of Eastern Asia and Australasia. A large American group, which is mainly represented by species from the Caribbean, has, until recently, also been subsumed under the Camaenidae. However, latest molecular phylogenetic studies showed that these species represent a different family, the Pleurodontidae. This molecular study also implies that the Bradybaeninae, previously treated as a distinct family within the Helicoidea, is a junior synonym of the Camaenidae.
