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]
