Families
The superfamily Plectopyloidea consists of the following families (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):
- Family Plectopylidae Möllendorff, 1898
- Family Corillidae Pilsbry, 1905 - with only one genus Corilla
- Family Sculptariidae Degner, 1923 - with only one genus Sculptaria
Distribution
Plectopylidae ranges across large parts of southeast Asia from Nepal to southern Japan.[3] Corillidae is the mainly Sri Lankan family.[3] Sculptariidae is the African family.[3]
Description
The Plectopylidae differ from the Corillidae by the presence of one or two vertical (= perpendicular to the suture) lamellae on the parietal wall, approximately a quarter to a half whorl behind the aperture.[3] In contrast, the Corillidae have only horizontal (= parallel with the suture) parietal plicae (in Corilla all plicae may be absent).[3]
