Xerocrassa Explained

Xerocrassa is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the subfamily Helicellinae of the family Geomitridae.^{[1] [2]}

Some species of Xerocrassa are instead considered to belong to the subgenus Xerocrassa, within the genus Trochoidea; in those cases the species are listed under the generic name Trochoidea. However, for other authors both taxa are not closely related being different genera.^{[3] [4]}

Taxonomy

The genus Xerocrassa is divided in 3 subgenera:

• Xerocrassa (Amandana) Fagot, 1891
• Xerocrassa (Xeroclausa) Monterosato, 1892
• Xerocrassa (Xerocrassa) Monterosato, 1892
