Antarctic hadal arcturids, with descriptions of a new genus and five new species (Isopoda: Valvifera: Arcturidae)

O.G. Kussakin & G.S. Vasina

Abstract. Six species of the family Acturidae are recorded from the western Antarctic, at depths more than 6000 m. All the six are new species belonging to six different genera, two of them new. Globarcturus angelikae was described by the authors earlier. Five new species (Rectarcturus tatianae, Neoarcturus caecus, Abyssarcturus averincevi, Cylindracturus leucophthalmus, and Antarcturus andriashevi) and the new genus Abysarcturus are described in this paper. All hadal arcturid species are probably blind; but two of them bear rudementary colourless eyes, and the others are without indication of eyes.
