Appalachina is a genus of small, air-breathing, land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Taxonomy
Henry Augustus Pilsbry[2] created what was then the subgenus Appalachina (under the genus Mesodon), a group of land snails in the family Polygyridae, for those snails with comparatively depressed (flat) shells and an open umbilicus (the center of the underside of the shell). The reproductive anatomy of these snails is important for distinguishing them from other polygyrids.[3]
Species
The genus Appalachina includes the following species:[3][4]
- Appalachina sayana (Pilsbry, 1906)
- Appalachina chilhoweensis (Lewis, 1870)
