Species-level taxonomy is reviewed for the Mediterranean Cerithiopsidae with a sculpture formed by two rows of beads. The two previously known species are assigned respectively to Dizoniopsis coppolae (Aradas, 1870) and D. concatenata (Conti, 1864) and are held as distinct from the fossil type species Dizoniopsis bilineata (Hörnes, 1848). Two additional species, which are found sympatrically with these in the Strait of Gibraltar, are described as new. Dizoniopsis micalii Cecalupo and Villari 1997 is reassigned to the genus Cerithiopsis.
