AB: The genus Tricolia (Phasianellidae) in the eastern Atlantic and Mediterranean is reviewed on the bases of radular morphology, shell characters and polychromatism. The taxa included within the T. pullus group are not clearly separable and are treated as geographical subspecies: T. pullus pullus, T. pullus picta, T. pullus azorica, T. pullus canarica . The case of T. tenuis is problematic since it is clearly separable from sympatric T. pullus pullus in most parts of the Mediterranean but transitional to T. pullus picta , towards the Atlantic. Other taxa are considered as having specific status since they are consistently separable when found in sympatric populations. These include T. speciosa, T. miniata, T. tingitana n.sp., T. petiti, T. nordsiecki and T. algoidea . The last two species are stated for the first time belonging to the Phasianellidae. The genus Epheriella , based on T. algoidea , is synonymized with Tricolia .
