Descriptions of new and little-known land snail taxa from Turkey, and establishment of a new genus (Gastropoda, Pulmonata: Lauriidae, Enidae and Vitrinidae)

Terrestrial molluscs show a high level of endemism (> 60%) in Turkey. Some 750 (sub)species are known; about one third of them have been described in the last four decades. However, many (sub)species are still waiting for its discovery. In this paper we describe 13 new (sub)species: Leiostyla paphlagonica subangulosa subspec. nov., Leiostyla eikenboomi spec. nov., Turanena (Turanena) elegantula spec. nov., Turanena (Turanena) andronakii salpinx subspec. nov., Imparietula inflexa spec. nov., Ljudmilena callosa spec. nov., Ljudmilena mariannae spec. nov., Clausilioides berendinae spec. nov., Clausilioides palatalis spec. nov., Amphiscopus sturmii marmoratus subspec. nov., Amphiscopus moolenbeeki spec. nov., Multidentula reducta spec. nov., and Megavitrina imperatoria spec. nov. The new genus Megavitrina has been established to accommodate the species imperatoria (Turkey: Nemrud Dağ) and libanica (Lebanon: various localities). Buliminus corpulentior is redefined, and notes are given for the almost forgotten Clausilioides filifer and Multidentula squalina acutior.
