Atlantica gueriniana is a species of small air-breathing land snail, a terrestrial gastropod mollusk presently in the family Gastrodontidae, [2] [3] but formerly in Discidae, the disk snails. [1]
The shell of these snails is shaped like a discus, or a lens, with a noticeable "edge" around the periphery of the whorls.
This species is mentioned in annexes IV and IV of the Habitats Directive. [4]
