Abstract

The generic allocation of Helix subaperta is clarified by using genetic data and morphological traits of the genital organs; its position within the hitherto monotypic genus Cantareus is corroborated. Further analysis of several specimens of Cantareus apertus from Algeria and Italy revealed that this taxon is composed of two species, C. apertus from Italy, and C. koraegaelius from Algeria. The morphological traits of the genital organs of all three species are discussed, and the definition of the genus Cantareus is amended. All three species confined to Cantareus are re-described, and the syntype specimen of H. aperta is illustrated.
