Etymology: Bathyraja: Greek, bathys = deep + Latin, raja, -ae = a ray (Raja sp) (Ref. 45335); lindbergi: Named for Dr. G. U. Lindberg, for his work on western North Pacific zoogeography (Ref. 75535).
Eponymy: Dr Georgii Ustinovich Lindberg (1894–1976) was a Russian ichthyologist and marine biologist who was a lecturer at Chita University and who was invited (1923) to the Far-Eastern University in Vladivostok where he established a coastal biological [...] (Ref. 128868), visit book page.

Wervels: 113 - 117. This species is distinguished from its congeners Bathyraja in having a whitish brown coloration on the ventral surface of the disk, contrasting the dark greyish brown on other parts; scapular spine absent; row of middorsal spines uninterrupted, running from before scapular arch to first dorsal (Ref. 75535).
Body shape (shape guide): other.
Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Depth range given by H. Ishihara (pers.comm. 07/07).
