It further differs from R. annulatus by a uniformly dark caudal-peduncle band (vs. band with an unpigmented central section) and 32-33 total vertebrae (vs. 34-35). It also differs from R. pulcher by fewer total vertebrate count (32-33 vs. 34-55). Additionally, it differs from R. epiblepsis by the pointed caudal-fin lobes (vs. rounded lobes), absence of very dark spots on the body (vs. such spotting) and faint serrations limited to the base of the anterior margin of the pectoral-fin spine (vs. well-developed serrations along the entire anterior margin) (Ref. 128485).
