Material examined : 484 specimens from the ocean and sea slopes of Kunashir , Iturup , Urup , Chyornye Bratya , Onekotan , and Paramushir Islands ( 30–300 m ) . Distribution : Kuril Islands ( 30–300 m ) ( Amano & Lutaenko 2004 ; Kantor & Sysoev 2005 ; Matsukuma 2017). Remarks: This species was described from six specimens collected at depths 54–218 m off Iturup Island ( Amano & Lutaenko 2004 ). Our study has shown that this species is widely distributed all along the Kuril Islands and in a slightly wider range of depths.
