The cryptic gastropod Alvania scuderii Villari, 2017, recently described from the Strait of Messina as new species inside the A. scabra (Philippi, 1844) group, was known by restricted areas of eastern and southern Sicily. Some records from the type locality and south-eastern Tyrrhenian sea, which provided new data on habitat and bathymetric range, also enlarged northward, in a further basin, the known areal. Such areal, that overlaps a Mediterranean western-eastern biogeographic boundary, may be considered a further clue of an hydrological front that is responsible of a WestMediterranean footprint more marked than in nearby North-westernmost areas

Abstract
The cryptic gastropod Alvania scuderii Villari, 2017, recently described from the Strait of Messina as new species inside the A. scabra (Philippi, 1844) group, was known by restricted areas of eastern and southern Sicily. Some records from the type locality and south-eastern Tyrrhenian sea, which provided new data on habitat and bathymetric range, also enlarged northward, in a further basin, the known areal. Such areal, that overlaps a Mediterranean western-eastern biogeographic boundary, may be considered a further clue of an hydrological front that is responsible of a WestMediterranean footprint more marked than in nearby North-westernmost areasPubblicazioni consigliate
