Theba is a taxonomic genus of air-breathing land snails, medium-sized pulmonate gastropod mollusks in the family Helicidae, the true snails. [2]
Theba is the type genus of the tribe Thebini. [3] The genus occurs in the Mediterranean Basin, in the Canary Islands, and in Morocco. [4]
Species within the genus Theba include:
Helicidae is a large, diverse family of western Palaearctic, medium to large-sized, air-breathing land snails, sometimes called the "typical snails." It includes some of the largest European land snails, several species are common in anthropogenic habitats, and some became invasive on other continents. A number of species in this family are valued as food items, including Cornu aspersum the brown or garden snail, and Helix pomatia. The biologies of these two species in particular have been thoroughly studied and documented.
Cantareus is a genus of air-breathing land snails, a pulmonate gastropod in the family Helicidae, the typical snails.
Helicella is a genus of small to medium-sized, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Helicellinae of the family Geomitridae, the hairy snails and their allies.
Hygromia is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Hygromiidae, the hairy snails and their allies.
Truncatella is a genus of very small land snails with an operculum, terrestrial gastropod mollusks in the family Truncatellidae. These small and minute snails live on land, very close to seawater. They walk with a strange looping action, and the adults have truncated shells. Many of the species are small enough to be considered micromollusks.
Hygromiidae is a taxonomic family of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
Xeromunda is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Helicellinae of the family Geomitridae, the harry snails and their allies.
Otala is a genus of land snails in the subfamily Helicinae of the family Helicidae.
Monacha is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Trochulininae Lindholm, 1927 of the family Hygromiidae, the hairy snails and their allies.
Rumina is a genus of medium-sized predatory land snails, terrestrial pulmonate gastropod mollusks in the family Achatinidae.
Xerocrassa is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the subfamily Helicellinae of the family Geomitridae.
Ferussacia is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Ferussaciidae.
Massylaea is a genus of air-breathing land snails, a pulmonate gastropod in the subfamily Helicinae of the family Helicidae, the typical snails.
Rossmaessleria is a genus of land snails in the subfamily Helicinae of the family Helicidae.
