A new taxon of Idyanthidae (Copepoda, Harpacticoida) from the deep sea of the Angola Basin

Multicorer samples from the deep sea of the Angola Basin yielded 19 species of Idyanthidae Lang, 1994 belonging to five genera. The taxon membership of the species was determined following (Phylogeny of Harpacticoida (Copepoda): Revision of “Maxilliped-asphalea” and Exanechentera. Cuvillier Verlag, Göttingen, 259pp.). Except for one species, Styracothorax gladiator Huys, 1993, all species are new to science. One of them is described here on the basis of females and males. It represents a new genus, Nematovorax gen. nov. One female of the new species N. gebkelinae, was found to hold a nematode between its mouthparts.
