POLYASCOPHORUS, A NEW GENUS OF ANCORABOLIDAE (CRUSTACEA, COPEPODA), INCLUDING THE DESCRIPTION OF 2 NEW SPECIES AND THE RE-ALLOCATION OF CERATONOTUS-GORBUNOVI

Two new species of copepods are described, one from the Barents Sea (A rctic), and the other from the Weddell Sea (Antarctic). Polyascophorus martinezi gen. et sp. n. and P. schminkei sp. n. belong to the Ancora bolinae Sars, 1909 (Copepoda, Harpacticoida, Ancorabolidae), because t hey share the following apomorphic characters: loss of exp A2, prolong ation of basis P1, enp P1 not prehensile, loss of first outer seta of exp 3 P2-P4. On the other hand, they differ in so many characters from all hitherto known taxa within Ancorabolinae that a new genus is esta blished. Ceratonotus gorbunovi (Smirnov, 1946) is transferred into the new genus Polyascophorus, due to several characters it shares with th e two new species described here.
