Cervinia langi n. sp. and Pseudocervinia magna (Copepoda: Harpacticoida) from the Beaufort Sea (Alaska, U.S.A.)

Two species of the family Cerviniidae have been collected from the Beaufort Sea off the coast of Alaska. Pseudocervinia magna (Smirnov, 1946) and Cervinia langi n. sp. were found in association. Lang (1936, 1948) described the new species as a variant of Cervinia synarthra Sars, 1911. However, C. langi is consistent and unique in the setation of its swimming legs and in details of the mandible and maxilliped. A key to the species and a table of salient morphological characters of the genus Cervinia are given. Appendages from the cephalothorax of P. magna are also figured, and its taxonomic position is discussed.
