Original diagnosis of Ebert, Alfaro-Shigueto, Velez-Zuazo, Pajuelo & Mangel, 2022 [31071]: A large Bathyraja species (to at least 1126 mm TL) with a rhombic disc, distinguished from other Peruvian species (as well as all other southeast Pacific congers) by a uniform black-to-chocolate or dark-plumbrown coloration, notably the same on both dorsal and ventral surfaces vs. dorsal and ventral surfaces different colors (except B. aguja); and an irregular spotted pattern on both dorsal and ventral surfaces vs. no spotting or, in B. aguja, two symmetrically arranged, large, white spots on dorsal surface at pectoral-fin bases and symmetrically arranged white spots along disc margins; additionally separated from Peruvian congeners by more precaudal vertebrae 79–81 vs. 62–71; and fewer pectoral-fin radials 69–70 vs. 72–83.
