New Records of Rare Psychrolutid Fishes (Psychrolutidae) in the Sea of Okhotsk

摘要

Two rare species of psychrolutid fish (Psychrolutidae) were found in the Sea of Okhotsk. Psychrolutes dolganovi was found at a depth of 142 m near Urup Island (southern Kuril Islands); earlier the species was known only from the holotype collected off the Pacific coast of Iturup Island. This species is recorded in the Sea of Okhotsk for the first time. P. pustulosus was collected at depths of 205-400 m along central part of Kuril Islands and in the northwestern part of the Sea of Okhotsk at depths of 240-294 m. A key to the species of the genus Psychrolutes inhabiting the northern Pacific Ocean is presented.
