Methodical Review of the Research about the Cave Fauna in Western Rhodopes Mts. (Bulgaria)

A review is presented of the existing information about cave fauna in Western Rhodopes. For simplicity, data about local caves and species in the karst forms are presented in two tables. The caves support a biodiverse ecology and are an important Bulgarian natural resource. The taxonomy will be a useful foundation for the development of further research in this or another cave, not only in this mountain, but also and in whole country. The information presented will be supplemented by further research in the field. Records about cave fauna are gathered by different sources ? catalogues, articles, books and web-adresses, which are for the moment the most valued base of information in the biospeleology in Bulgaria.
