North Pacific: Sea of Japan to the Bering Sea and to Bodega Bay, central California, USA. Past works (e.g. Hart 1973, Ref. 6885) recognized two subspecies, Pallasina barbata barbata occurring in the Bering Sea and along the Asian coast through the Sea of Okhotsk to Japan and Pallasina barbata aix occurring from the Gulf of Alaska to California, USA, as well as Kamchatka and Japan. Sheiko 1993 on the other hand recognizes both Pallasina barbata and Pallasina aix as valid species (Ref. 26282).
