This cave is one of the numerous re-emergences of the underground Gardon river. 2mm. The species-name honours the purposeful and hard-working zoologist Walter Klemm (1898–1981), famous for his vast knowledge of European land and freshwater snails, thanks to Dr. R. Sturany who steered him towards malacology.
