Eulagisca is a genus of marine polychaete worms belonging to the family Polynoidae. 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.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
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.
Species
Five species of Eulagisca are recognised as of August 2020:
