Abstract

In this dissertation, integrative taxonomy was used to unravel cryptic species in different terrestrial snail groups. With the inclusion of mitochondrial and nuclear DNA, shell morphological features, histological sections, and the investigation of the morphology of the radula, it was possible to describe the new genus Iberozospeum Jochum, Kneubühler, Prieto & Neubert, 2022 and a new species from Spain (Chapter 1). The focus of the work was on the resolution of the species complex within the hairy snail genus Trochulus Chemnitz, 1786. A rich sampling from almost the entire distribution area of the genus made it possible to clarify the complicated taxonomy of Trochulus (Chapters 2 and 3). In addition, phylogenetic problems within the ellobiid micro snail genera Zospeum Bourguignat, 1856 and Carychium O.F. Müller, 1773 (Chapter 4) were resolved.
