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 ( Western Mediterranean) being present in all major islands and in several small islets. [2] 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.
For some authors, [3] Allognathus include two subgenus, Allognathus s. str., that is monospecific, and Iberellus Hesse 1908, that includes at least two species.
Species within the genus Allognathus include: [2] [3]
- Allognathus campanyonii (Rossmässler, 1839)
- Allognathus graellsianus (Pfeiffer, 1848) - type species
- Allognathus hispanicus (Rossmässler, 1838)
