Greece, a second hotspot of Bythinella spp. (Gastropoda: Bythinellidae) in Europe, with the description of two new species. — Recently, many Bythinella species have been described from Greece, with the result that 34 species are already known in this country. New investigations revealed two additional species from Lefkas and Parnassos mountains. For the new species delimitation, morphometric characters and multivariate cluster analyses were used, which showed distinctiveness of the species. Additionally, an overview of all known species of Greece with pictures of the shells and short descriptions are given. This is the second highest species richness spot of Bythinella in Europe, after the 52 Bythinella species known in France.
