This work was written as cumulative doctoral thesis based on publications in peer reviewed international journals. Aim of the studies was to analyse the range of the intraspecific variability of some representatives of the family Lymnaeidae as well as to find out which value should be given to the morphological and anatomical characters used for taxonomy and systematics at all. For this a new integrative approach of morphology and molecular genetics was sought. It was also important to find out how own reconstructions of phylogenetic trees based on nuclear and mitochondrial markers confirm or refute existing views on taxonomy and systematics of the Lymnaeidae. First own morphological analyses of Palaearctic representatives of the genus Radix checked by molecular genetics reveal that shell morphology, mantle pigmentation, length ratio of Praeputium to penial sheath, length of the duct of the bursa copulatrix and shape of the bursa show more variability in this characteristics as recognised for these species in literature. They are, contrary to previous assumptions, to a large extent not specific for single species. With molecular genetic methods clearly distinguishable species may have the same shell morphology and mantle pigmentation and could be not clearly differentiated by anatomical characters in many cases. It can be concluded, also on the basis of own studies of other representatives of the family Lymnaeidae, that to these characters was given an importance for taxonomy and systematics by most of the malacologists that they obviously do not have because of their high plasticity. Molecular genetic methods allow a new interpretation of the importance of morphological and anatomical characters and a more objective definition of species and genera. Based on the new findings on variability of morphological characters a new determination key for the representatives of the genus Radix in central Europe was elaborated. It enables the determination of more Radix forms
