The nomenclature of the Rotifera: annotated checklist of valid familyand genus-group names

In order to help elucidate confusion in the nomenclature of Rotifera (5 Syndermata), an updated checklist is provided, including corrections and additions of family- and genus-group names presently considered valid in the Phylum. The species diversity of the Rotifera is illustrated by estimates of the number of valid, named species in each genus. The validity of Paranuraeopsis Koste, 1974 is rejected based on a re-evaluation of its diagnostic features. It is synonymized with Anuraeopsis Lauterborn, 1900. The name Beauchampiella Remane, 1929 is recognized as the valid replacement name for Eudactylota Manfredi, 1927 non Walsingham, 1911 ( Insecta), with preference over Manfredium Gallagher, 1957. The priority of Lepadellidae Harring, 1913 over Colurellidae Wesenberg-Lund, 1930 is commented upon.
