Abstract
    Re-examination of copepod material, collected from the northern Gulf of Mexico and previously identified as Zausodes arenicolus C.B. Wilson, 1932 (Harpacticoida, Harpacticidae), resulted in the discovery of three new species of the Zausodes complex. Phylogenetic analysis identified four distinct lineages within this complex which are attributed generic status. Zausodes C.B. Wilson, 1932 is redefined to include only Z. septimus Lang and the type species Z. arenicolus which is completely redescribed. A new genus Mucropedia is proposed to accommodate two new species from the Gulf of Mexico, M. kirstenae and M. cookorum. Z. biarticulatus Ito, 1979 from the Japanese Bonin Islands is transferred to Archizausodes gen. nov. and regarded as the most primitive member of the Zausodes complex. All other species are grouped in Neozausodes gen. nov., including N. shulenbergeri sp. nov. from the Gulf of Mexico and N. areolatus (Geddes, 1968a) comb. nov. which is completely redescribed on the basis of type material. Z. ductus Krishnaswamy, 1954 is ranked species incertae sedis in the family Harpacticidae. The sister group relationship between Perissocope Brady, 1910 and the Zausodes complex is discussed. Lang's (1944, 1948) subfamilial division of the Harpacticidae is abandoned.
