Schileykula
Schileykula is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Orculidae. All of the species and subspecies in this genus inhabit Turkey, with the exception of the subspecies Schileykula scyphus crass (Pilsbry, 1922), which lives in Iran.

Species belonging to the genera Schileykula and Orculella are indistinguishable based on shell characters only. They differ however in the genitalia, primarily in the presence (Orculella) or absence (Schileykula) of a penial appendix.
In Sch. batumensis and Sch. trapezensis the reproductive isolation is incomplete.
