Justification: A little-known deepwater skate recorded from off Brazil and Chile. Holotype was taken at a depth of 1,200 m. Maximum observed size off Chile 75 cm total length (TL). Nothing known of its biology. Taken as bycatch of artisanal longline fisheries for Patagonian toothfish Disostichus eleginoides, however, specific catch data are not available. Insufficient information to assess the species beyond Data Deficient. |
