Sensiava longiseta (Copepoda, Calanoida): a new genus and species from the abyss of the Weddell Sea
Sensiava longiseta gen. et sp. nov. is described from male specimens collected at abyssal depths above the seabed in the Weddell Sea (Southern Ocean). Segmentation and setation of the swimming legs of the new species are typical of the superfamily Clausocalanoidea. Although the new genus shares the...
