. 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 ''Schileykula batumensis, Sch. batumensis'' and ''Schileykula trapezensis, Sch. trapezensis'' the reproductive isolation is incomplete.
