ABSTRACT: Masikia Millidge, 1984 was known to encompass two species prior to this study. The present review reveals three distinct morphospecies all represented by both sexes: M. indistincta (Kulczyński, 1908), M. caliginosa Millidge, 1884 and M. bizini sp.n. Generic alignment of M. relicta (Chamberlin, 1949) known from female holotype from Vermont is doubtful. Masikia caliginosa Millidge, 1884 stat.rev. is removed from synonymy with M. indistincta. Its male is described for the first time. All three species are illustrated in detail and their distribution is mapped. In several localities M. caliginosa and M. indistincta were found to be sympatric.

KEY WORDS: Araneae, Erigone-group, new species, Arctic, tundra zone, Russia, Alaska, Canada, sea marshes.
