| Remarks | Males differ from females by having long, very dense hypertrophied odontodes on sides of head, and on dorsal surface of branched pectoral-fin rays. Odontodes in dorsal region giving hispid appearance to fish; and unbranched pectoral-fin ray thickened (Ref. 75788). |

| Diagnosis |
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). |
