Description

edit

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.[1]

Five species of Eulagisca are recognised as of August 2020:[2]
