spirilla , Hyaloscala [ Epitonium spirillum (Monterosato, 1890) ] ( Figures 11A, B )

1890a: 150 [XXXVIIIa: 904]—available name

Type material. MCZR–M–23467 —17 sh “ Sc. spirilla Monts Nat. Sic. 1890 p. 11 Palermo” “ Scalaria spirilla n. sp. Monts. ms. Palermo”

Type locality. Described from Palermo (Sicily).

Remarks. Recorded by MolluscaBase (2018) as a synonym of Epitonium clathratulum (Kanmacher, 1798) . However, Epitonium spirillum differs from E. clathratulum in its smaller size, fewer and more lamellose axial ribs, squared whorls, larger and more acute protoconch. We consider E. spirillum as a valid species [new status] that replaces E. clathratulum in most of (if not all) the Mediterranean.
