A new species of Lycenchelys (Perciformes: Zoarcidae) from the Pacific coast of northern Japan

 Lycenchelys tohokuensis sp. nov. is described from five specimens, 199–270 mm SL. Unknown before 1997, specimens were collected along the Pacific side of the Tohoku coast, from off Aomori to Fukushima prefectures at depths of 543–709 m. The species differs from all congeners in the northwestern Pacific chiefly in the lack of pelvic fins, having a double lateral line configuration, relatively low vertebral counts, two rows of palatine teeth, and its head pore pattern. The new species does not appear to be closely related to any other northwestern Pacific Lycenchelys including the only other one without pelvic fins, Lycenchelys fedorovi Anderson and Balanov, 2000.
