We compared shell shapes genital morphology two species. analyzed mitochondrial COI nuclear 18S ribosomal RNA ITS1gene fragments in 39 specimens H. ten locations entire distribution range these species, together with 13 widespread lucorum pomatia 1758. Based on alone, most individuals can be discriminated using multivariate approaches. have different flagellum/diverticulum ratios, foot coloration a fully diagnostic morphological character. Mole...
