Desmosomatidae (Isopoda, Asellota) from bathyal and abyssal depths in the Norwegian, Greenland, and North Polar Seas

Abstract

Abstract Desmosomatidae from bathyal and abyssal arctic waters were collected in the Norwegian and Greenland Seas during the NORBI expedition in July-August 1975 and in the Norwegian Sea during cruises with R/V Halkon Mosby in March, June, and August 1981, and in January and November 1982. Desmosomatids from the North Polar Sea were sampled during an expedition with the icebreaker Ymer in July 1980. Seven species were found; Whoia dumbshafensis sp. nov., Eugerda arctica sp. nov., Eugerda reticulata (GURJANOVA, 1946), Desmosoma strombergi sp. nov., Eugerdella hessleri JUST, 1980, Cryodesma agnari gen. nov., sp. nov., and Oecidiobranchus nanseni JUST, 1980. W. dumbshafensis, D. strombergi, and E. hessleri were only found in the Norwegian Sea, E. arctica and E. reticulata in the Norwegian Sea and the North Polar Sea, and C. agnari and O. nanseni in the Greenland Sea, the Norwegian Sea, and the North Polar Sea.
