Caudacalanus (Copepoda, Calanoida): a new benthopelagic genus from the abyssof the tropical South Atlantic and Southern Ocean
Two species of a new spinocalanoidean genus, Caudacalanus, are described from female specimens collected during the German expeditions ANDEEP I–II in 2002 and DIVA-1 in 2000 at abyssal depths above the seabed in the Southern Ocean and tropical waters of the South Atlantic. Segmentation and setation...
