| Abstract |
Three new species of Rotifera belonging to the genus Encentrum (Monogononta, Dicranophoridae) are described and illustrated. Encentrum barti sp.nov. was found among algae in the Eastern Scheldt estuary, the Netherlands. Its main distinguishing taxonomic features are the rostrum provided with a triangular projection, the conical and slightly incurved toes, and the characteristic trophi. Encentrum listensoides sp.nov. was collected among algae in the Eastern Scheldt estuary, the Netherlands. The main diagnostic features of this new species are the foot composed of three pseudosegments, a single pair of large pedal glands, and the trophi showing asymmetrical unci, evenly curved manubria, and preuncinal teeth set at a right angle to the axis. Encentrum tenuidigitatum sp.nov. was found in hygropsammon of a bight of the North Sea in Belgium. It is diagnosed by its slender, acutely pointed toes, and the trophi bearing a tooth on the inner margin of the subbasal rami chambers. |
