Arctic Ocean Copepoda of the Genera Lubbockia, Oncaea, and Epicalymma (Poecilostomatoida: Oncaeidae), with Remarks on Distributions

Abstract

ABSTRACT Systematics and distributions for three genera of Arctic Ocean oncaeid copepods are reviewed: two species of Lubbockia, one a new record from the Arctic Ocean; seven species of Oncaea, with only one recorded earlier from the Arctic Ocean, two new species, and records of four species recently described from the subantarctic and antarctic southwest Pacific Ocean (Heron, 1977); and five species of Epicalymma, two new species, two with a new combination, and two species known from the southwest Pacific Ocean. Arctic Ocean oncaeids appear to have broad geographical distributions. Thirteen of the Arctic Ocean oncaeids that are discussed in this study were found in samples from at least one other area: seven species in the northeast Pacific Ocean, including one from Puget Sound, Washington; twelve species in the Norwegian Sea; and six species in the southwest Pacific Ocean. Oncaea englishi Heron, 1977, was found in all of these areas except Puget Sound. The fourteenth species, Lubbockia brevis Farran, 1908, was originally described from the North Atlantic Ocean.
