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).
