Wesenbergia Hartman, 1955 (Annelida, Hesionidae) is both preoccupied and a junior homonym of Wesenbergia Kryger, 1943 (Hymenoptera, Pteromalidae), and must be renamed. Elisesione nom. n. is proposed as a replacement name, derived from the combination of the first name of the discoverer, Elise Wesenberg-Lund, and Hesione Savigny in Lamarck, 1818. Elisesione mezianei sp. n., is described from the Wallis and Futuna islands (southwest Pacific). A key to separate E. mezianei sp. n. from its congener E. problematica (Wesenberg-Lund, 1950) is included; further, the record of E. problematica for 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 wide vs 8–12 times longer than wide in the type species).
