On the ground of an extensive study of topotypes and of the shell morphology documented in comparable Mediterranean populations, Granulina pusaterii Smriglio & Mariottini, 2003 described from the Tunisian Plateau is proved to belong to the natural variability of G. melitensis Smriglio, Mariottini & Rufini, 1998 and it is proposed as junior synonym name of the latter.
