Diagnosed from all congeners by its unique color pattern composed of one dark, wide band covering most of the distal one-half of all fins. Differs from other species in the rocky group, except Rineloricaria microlepidogaster, by its snout with roundish naked area, which generally reaches to anteriormost pore of infraorbital ramus of sensory canal (vs. roundish naked area not reaching to anteriormost pore of infraorbital ramus of sensory canal or an elongate naked area) (Ref. 75788).
