The genital morphology of 120 specimens of 22 taxa from 44 populations was investigated, and a new general description of the genital morphology of the genus is provided. Additionally, 26 specimens of 14 taxa of five genera (Mollus-caBase 2021) of Alopiinae (Mauritanica, Charpentieria, Stigmatica, Gibbularia, Papillifera) were included in the genetic analyses. New anatomical structures are described: the parapseudopapilla for Charpentieria dyodon and the hemipapilla for Charpentieria stenzii. In the phylogenetic tree based on COI sequences, the species of the genus Siciliaria s. l. from northwestern Sicily were found within two separate highly supported main clades. In the tree based on the nuclear ITS2 marker sequence, resolution was considerably lower but it partially confirmed the mitochondrial tree. The genus Sicania Tomlin, 1929 (corresponding to main clade II in the trees) is reintroduced. Siciliaria scarificata did not appear in one of the two main clades but clustered together with Mauritanica perinni polygyra. Concerning monophyly of species, only the widely distributed S. calcarae was paraphyletic in the COI tree, a finding that has to be investigated further with multiple marker sequences. For the other genera (Mauritanica, Charpentieria, Stigmatica,
