Checklist of the Crustacea (Cladocera, Ostracoda, Copepoda) fauna in the active floodplain area of the Danube (1843-1806, 1669 and 1437-1489 rkm)

Abstract

A checklist of Crustacea containing 90 taxa from the main arm and the active floodplain of the River Danube is given. Nine Cladocera species (Anchistropus emarginatus, Daphnia ambigua, Holopedium gibberum, Monospilus dispar, Pleuroxus uncinatus var. balatonicus, Pseudochydorus globosus, Scapholeberis rammneri, Wlassicsia pannonica) and two Copepoda species (Cyclops insignis, Cyclops scutifer) are new and rare species of the sampling area. The Ostracoda fauna of this region was nearly entirely undiscovered, 15 species were recorded. Among them Bradleycypris obliqua, Bradleystrandesia reticulata, Paracandona euplectella and Prionocypris zenkeri are rare species in Hungary.
