Patera is a genus (or subgenus under Mesodon) of terrestrial snails in the family Polygyridae. The name is from the Latin patera, meaning a saucer, and refers to the highly depressed, saucer-like shape of the shells of these snails. In addition to flattened shells, members of the group have an imperforate umbilicus, and a single tooth, on the parietal wall of the aperture. [2]
They are known only from the eastern United States. [3]

- Patera appressus
- Patera jonesianus
- Patera panselenus, Virginia bladetooth snail
