Terrestrial gastropods (Mollusca, Gastropoda) of the Bulgarian part of the Alibotush Mts

This work presents results of two years collecting efforts within the project “The role of the alpine karst area in Bulgaria as reservoir of species diversity”. It summarizes distribution data of 44 terrestrial gastropods from the Bulgarian part of Alibotush Mts. Twenty-seven species are newly recorded from the Alibotush Mts., 13 were confirmed, while 4 species, previously known from the literature, were not found. In the gastropod fauna of Alibotush Mts. predominate species from Mediterranean zoogeographic complex. A large part of them is endemic species, and this demonstrates the high conservation value of large limestone areas in respect of terrestrial gastropods.
