Discovery of Novocriniidae (Copepoda, Harpacticoida) from cold-water corals in the Porcupine Seabight (NE Atlantic), with description of a new species of Atergopedia Martínez Arbizu & Moura, 1998

AbstractThe female of Atergopedia longicaudata sp. n. is described from dead cold-water coral fragments collected from the Porcupine Seabight (NE Atlantic). The new species is the fourth representative of the family Novocriniidae (Copepoda, Harpacticoida); it can be distinguished from its congeners by the elongate caudal rami and the ancestral armature on enp-3 of P1. Rediscovery of Atergopedia vetusta Martínez Arbizu & Moura, 1998, originally described from the Arctic Barents Sea, results in corrections to the species description. Archaeotisbe confluenta Kornev & Chertoprud, 2008 is transferred to the genus Atergopedia Martínez Arbizu & Moura, 1998, and Archaeotisbe Kornev & Chertoprud, 2008 is newly treated as a junior synonym of Atergopedia. Diagnoses (as ground patterns) for the two novocriniid genera (Atergopedia and Novocrinia Huys & Iliffe, 1998) are provided, and autapomorphies are indicated
