Xolotrema is a genus (or subgenus under Triodopsis ) of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Pilsbry (1940) [3] characterized the shell of Xolotrema (which he considered to be a subgenus) thus:
"Triodopses, in which the inner margin of the basal lip has a long bladelike lamella, terminating at a notch where it joins the outer arc of the lip; the embryonic whorls are covered with close retractive radial striae (subobsolete in T. fosteri)."
Species within the genus Xolotrema include:
Allognathus is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Helicidae, the true snails. The genus is endemic to the Balearic Islands being present in all major islands and in several small islets. The genus colonized the archipelago from the south-eastern Iberian Peninsula during the Middle Miocene, throughout a land-bridge connection. The different species belonging to Allognathus live in crevice rocks or under stones.
Mesodon is a genus of land snails 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.
Euglandina is a genus of predatory medium- to large-sized, air-breathing, land snails, terrestrial pulmonate gastropod mollusks in the family Spiraxidae.
Liguus is a genus of large tropical air-breathing land snails, more specifically arboreal or tree snails, terrestrial pulmonate gastropod mollusks in the family Orthalicidae.
Neohelix 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.
Ancotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Haplotrematidae.
Appalachina is a genus of small, air-breathing, land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Daedalochila is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Polygyridae.
Euchemotrema is a genus of small, 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.
The Helminthoglyptinae are a subfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks within the family Xanthonychidae.
Vespericola columbiana, common name the northwest hesperian, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Polygyridae.
Xolotrema notata is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Polygyridae.
Volutaxis is a genus of predatory air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Spiraxidae.
