Appalachina is a genus of small, air-breathing, land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
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]
The genus Appalachina includes the following species: [3] [4]
Cryptomastix is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Polygyra is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Stenotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae. These are typically small to medium-sized snails, with a velvety or hairy shell surface, and a narrow aperture which is usually closely guarded by well-developed "teeth".
Vespericola is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Polygyridae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.

Neohelix is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Xolotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Allogona is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Haplotrematidae is a taxonomic family of predatory air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Haplotrematoidea.
Ancotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Haplotrematidae.
Daedalochila is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Polygyridae.
Webbhelix is a genus of North American land snails, terrestrial pulmonate gastropod mollusks in the family Polygyridae. The genus contains several taxa which were previously included under the name Triodopsis multilineata.

Praticolella is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Lobosculum is a genus of small air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Linisa is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Polygyrinae of the family Polygyridae.
Daedalochila uvulifera, common name the peninsula liptooth, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Polygyridae.
