[2] A large American group, which is mainly represented by species from the Caribbean, has, until recently, also been subsumed under the Camaenidae.
[3][4] This molecular study also implies that the Bradybaeninae, previously treated as a distinct family within the Helicoidea, is a junior synonym of the Camaenidae.
The shells of some taxa can be vividly coloured, showing banding or other conspicuous patterns, but others are plain and uniform.
[5] In order to retain the Camaenidae as a monophyletic clade, the Neotropical Pleurodontidae will need to be removed as an independent family and the Bradybaenidae will need to be included.
[10] The new taxonomy of the gastropods, published in 2017 and accepted by WoRMS, gives the following subfamilies:[11] As of March 2023, WoRMS accepts four subfamilies:[12] Currently, the following genera are accepted within the family Camaenidae:[13][14] Taxa with main occurrence in South-East Asia Taxa with main occurrence in Papua New Guinea to Solomon Islands Australian genera In Australia, the Camaenidae comprise 131 currently recognized genera, most of which are endemic to the continent.
