A new clausiliid species and genus from northern Peru, Symptychiella annae n. gen. n. sp., is described. The unique character combination of its shell (without neck keel, non-apostrophic aperture formation, one single lamella instead of superior and inferior lamellae, G-type clausiliar) does not allow a classification within one of the known subfamilies.
