The genus includes 5 species which are all found in the Southern and Antarctic Oceans and are notable for reaching a large size, 180 mm or more long, larger than any other species of Polynoidae.<ref name=pettibone1997>Pettibone, Marian H. 1997. Revision of the scaleworm genus ''Eulagisca'' McIntosh (Polychaeta: Polynoidae) with the erection of the subfamily Eulagiscinae and the new genus ''Pareulagisca''. Proceedings of the Biological Society of Washington, 110(4): 537–551</ref>
==Description== Species of ''Eulagisca'' have 35–41 segments and 15 pairs of elytra. The lateral antennae are undivided and inserted terminally on the prostomium . There is a distinctive dorsal fold ("nuchal flap" in the taxonomic literature) on segment 2, and unlike the related genus ''Pareulagisca'', in ''Eulagisca'' all notochaetae are stout and have blunt tips.<ref name=pettibone1997></ref>
