Description
Summary:Studies on the newly collected materials of Eubrachiella antarctica (QUIDOR, 1906) from Dissostichus eleginoides near Heard Island (taken during the Australian National Antarctic Research Expedition) and Eubrachiella gaini dorsituberculata KABATA and GUSEV, 1977 from Trematomus bernacchii (taken from Liitzow-Holm Bay, Antarctica, during the cruise of the 35th Japanese Antarctic Research Expedition) revealed the necessity of reconsideration of the systematic status of the genus and removing from it two nominal species: Eubrachiella sublobulata BARNARD, 1955 and Eubrachiella mugilis KABATA et al., 1971. History and systematics of the genus Eubrachiella WILSON, 1915 are discussed in detail and a new diagnosis of the genus is proposed. With this new treatment, copepods of the genus Eubrachiella become more homogenous and, at the same time, show strong preference for parasitism on Antarctic fishes of the Bathydraconidae, Channichthyidae, and Nototheniidae.
