Abstract
A new dicranophorid rotifer, Encentrum (Parencentrum) walterkostei n.sp., is described from an oligotrophic alpine lake. The species was abundant in the psammolittoral of the ‘Unterer Schwarzhornsee’, 2543 m above sea level. The main distinguishing taxonomic features of the new species are long, swordshaped toes and only four vitellary nuclei. Its known occurrence in the sandy substrate of only one lake suggests a stenobiontic nature of this apparently oligothermic new species. Taxonomic problems associated with the Encentrum/Dicranophorus group are briefly discussed.
