From Wikipedia, the free encyclopedia
Ayna is a monotypic genus of air-breathing land snails, terrestrial gastropod mollusks in the family Enidae. The sole species in the genus is Ayna mienisi.[2] It was described as Zebrina (Ramusculus) mienisi. The genus Ramusculus however is a monotypic genus only distantly related to Ayna.

A. mienisi is a chirally enantiomorphic species. This means that some specimens have sinistral (left-coiled), others dextral (right-coiled) shells. The sinistral and dextral specimens form "clear" populations but can by found sympatrically as well. The sinistral specimens were described as a species (Ramusculus laevitortus Schütt, 1995) differs from the dextral Ramusculus mienisi. The species inhabits a relatively small area in Erzurum Province, northeastern Turkey.
