Plesioscolecithrix (Copepoda, Calanoida, Scolecitrichidae): a new genus, and a new species from the high Antarctic Weddell Sea (Southern Ocean)
Both sexes of Plesioscolecithrix juhlae gen. et sp. nov. are described from the Weddell Sea shelf, Antarctic, in near-bottom water layers from 167 to 254 m. The new genus has segmentation and setation of the swimming legs P1-P4 typical of the Clausocalanoidea. With the group of clausocalanoidean fam...
