Elasmobranchii 板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) > Rajiformes (Skates and rays) > Rajidae (Skates)
Etymology: Raja: Latin, raja, -ae = a sting ray (Raja sp.) (Ref. 45335).
  More on authors: Fricke & Al-Hassan.

Issue
The species does not belong to the genus Okamejei, evidenced e.g. by its overall appearance. Due to the lack of an adult male specimen, it is currently placed as incertae sedis in the general genus Raja (Ref. 101518).
