Issue
The large sequence divergences among B. eatonii from the Kerguelen Plateau and from the South Atlantic-Ross Sea provide evidence for two species in these regions. The species, referred to as Bathyraja sp. (cf. eatonii) from the Antarctic continental shelf and slope is a species distinct from B. eatonii. from the Kerguelen Plateau (the type locality) and thus is a new and undescribed species until it is formally described and named (Ref. 93260).

Southern Ocean: common on the Kerguelen Plateau, around South Orkney and South Shetland islands. In the Antarctic Peninsula, it occurs in the northeastern Weddell Sea and on Gunnerus Ridge. A single record comes from the Pacific Ocean sector, in the Ross Sea. Southeast Pacific: Chile (Ref. 9068).
南極海: 常見於克魁嶺高原, 在奧克尼群島南方部與雪特蘭群島南部周圍。 在南極半島中，它出現於東北方的威德爾海中與在 Gunnerus 脊上。 在羅斯海洋中,一個記錄來從太平洋地區。 東南太平洋: 智利.(參考文獻 9068)
