Abstract This study introduces two new species, Belgrandiella mimula and B. wawrai. The anatomy of B. parreyssii is described for the first time. ‘Graziana’ austriana is placed in the genus Belgrandiella. This increases the number of Austrian Belgrandiella species to seven. A cladistic analysis demonstrates that this East Alpine radiation is well defined by anatomy and probably deserves taxonomic separation. The subdivision of the Austrian species of Belgrandiella into two groups is consistent with biogeography. All seven species are extreme endemics and highly endangered, as each is found only in a single spring or a single, isolated valley.
