Abstract
A new dicranophorid rotifer, Encentrum (Parencentrum) walterkostei n.s p., is described from an oligotrophic alpine lake. The species was abu ndant in the psammolittoral of the 'Unterer Schwarzhornsee', 2543 m ab ove sea level. The main distinguishing taxonomic features of the new s pecies are long, sword-shaped toes and only four vitellary nuclei. Its known occurrence in the sandy substrate of only one lake suggests a s tenobiontic nature of this apparently oligothermic new species. Taxono mic problems associated with the Encentrum/Dicranophorus group are bri efly discussed.
