A revaluation of the Eurycopinae (Crustacea, Isopoda, Munnopsidae) with a description of Dubinectes gen. nov from the southern Atlantic deep sea

A new genus of Eurycopinae (Munnopsidae), Dubinectes gen. nov., is described for Eurycope acutitelson Menzies, 1962, E. nodosa Menzies, 1962 and two new species, collected from the Weddell Sea, Southern Ocean. The new genus is distinguished by the distinctive shape of the pleotelson posterior margin and the uropod protopod angled at midlength, along with the long rostrum of a large head, overhanging frons, reduced distomedial lobe of article 1 of antenna 1, the produced male pleopod 1 distolateral lobes and the distinct shape of the male pleopod 2. Descriptions of the new genus, two new species and redescriptions of two previously described species are presented, as well as a new diagnosis of the subfamily Eurycopinae, the genus Eurycope and a key to the genera of Eurycopinae.
