title: Elisesione, a new name forWesenbergiaHartman, 1955, and the description of a new species (Annelida, Hesionidae).
abstract: WesenbergiaHartman, 1955 (Annelida, Hesionidae) is both preoccupied and a junior homonym ofWesenbergiaKryger, 1943 (Hymenoptera, Pteromalidae), and must be renamed.Elisesionenom. n.is proposed as a replacement name, derived from the combination of the first name of the discoverer, Elise Wesenberg-Lund, andHesioneSavignyinLamarck, 1818.Elisesione mezianeisp. n., is described from the Wallis and Futuna islands (southwest Pacific). A key to separateElisesione mezianeisp. n.from its congenerElisesione problematica(Wesenberg-Lund, 1950) is included; further, the record ofElisesione problematicafor Japan should be regarded as a distinct species because it has palps shorter than antennae (subequal in the type species), and shorter neurochaetal blades (7-9 times longer than widevs8-12 times longer than wide in the type species).
