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 (Eumida) parvicirrus Perkins, 1984;
Eulalia sandwichensis Ushakov, 1975;

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
