A revision of the genus Sige Malmgren (Polychaeta: Phyllodocidae)

The genus Sige Malmgren, 1865 is revised and the type species S.fusigera Malmgren, 1865, redescribed from syntypes and newly collected topotype material. Based on examination of type specimens, six species described from other genera are transferred to Sige: Pirakia brunnea Fauchald, 1972; Vitiazia dogieli Ushakov, 1953; Eulalia longocirrata Stop-Bowitz, 1948; Eumida (Eumidaj parvicirrus Perkins, 1984; Eulalia sandwichensis Ushakov, 1975; Eulalia sigeformis Annekova, 1937. The genus Vitiazia Ushakov, 1953, being monotypic, becomes a junior synonym to Sige. Pirakia lanceolata Hartman & Fauchald, 1971 is synonymized with Sige longocirrata (Støp-Bowitz, 1948) and Sige oliveri sp. nov. is described from western Norway and Sweden. Ten species are recognized as belonging to Sige . The relationships of Sige to other genera are discussed.
