Plectopyloidea is a taxonomic superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the informal group Sigmurethra.
The superfamily Plectopyloidea consists of the following families (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):
Plectopylidae ranges across large parts of southeast Asia from Nepal to southern Japan. Corillidae is the mainly Sri Lankan family. Sculptariidae is the African family.
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. In contrast, the Corillidae have only horizontal (= parallel with the suture) parietal plicae (in Corilla all plicae may be absent).
