A new species of Eurycopinae (Munnopsidae) Eurycope crassiramis sp. nov. is described from the bathyal of the Weddell Sea, Southern Ocean. The new species is most similar to E. gaussi Wolff, 1956. Both species can be distinguished from all other species of this genus by the short cephalon and ambulosome (each length in the new species is 0.1 body length), a rostrum equal or subequal to medial cephalic length, a uropod with very broad rami and a protopod not broadened medially, and the peculiar form of the male pleopod 1. The new species differs from E. gaussi by the following characters: a lacinia mobilis with 6 denticles, a mandibular spine row with 6–7 setae, and a distolateral margin of male pleopod 1 broadly rounded, without projecting corners.
