A new species of Anatoma (Vetigastropoda: Anatomidae) from the Strait of Gibraltar

A new species of the genus Anatoma Woodward, 1859, collected by the BALGIM expedition (1984) from the Atlantic entrance of the Strait of Gibraltar is described and figured. The new species is compared with other Anatoma species reported in this and other areas, from which it is distinguished by the axial sculpture of the shell with unusually numerous riblets. The large number of species of this genus found in the studied area highlights the importance of deep-sea research, revealing unexpected biodiversity and suggesting further exploration opportunities.
