Bembidion species (Coleoptera: Carabidae) are abundant along stream and river margins. We evaluated data on Bembidion community composition of 185 riparian sites throughout Central Europe and adjacent areas. Cluster analysis revealed 21 distinct groups of Bembidion community types (based on quantitative data). Two main clusters can be distinguished: while the first one is restricted to sites characterised by coarse gravel, the second cluster is made up of sites dominated by fine sediments. A cluster analysis based on qualitative data revealed 23 groups of species with similar distribution patterns. The first main cluster is composed of species, most of which prefer coarse sediments and are mainly found on large gravel bars accompanying rivers in the Alps and the high mountainous areas. The second cluster comprises 31 species, which almost entirely prefer fine sediments (sand, silt and loam) and avoid coarse gravel. Habitat requirements for 65 Central European riparian Bembidion species are specified. The tight habitat binding of Bembidion species, especially in terms of substrate specificity, may reveal riparian Carabids to be very important for stream typology and assessment purposes.
