Distinguished from its congeners by the following characters: presence of transverse dark bands on pectoral-,pelvic- and anal-fin rays (vs. absence); 31 vertebrae (vs. 32), and by anterior portion of the compound supraneural-first dorsal-fin proximal radial contacting the neural spine of the 9th vertebra (vs. 10th). Differs from Rhinolekos garavelloi by the larger post-anal length (34.7-37.7% in SL vs. 29.0-34.6%); smaller thoracic length (14.7-18.0% in SL vs. 18.1-20.8%); and fewer plates in the dorsal series (24-28 vs. 30-35). Can be diagnosed from Rhinoleko schaeferi by the absence of premaxillary and dentary accessory teeth (vs. presence); and 21-24 mid-dorsal plates (vs. 18-20) (Ref. 86681).

Description: Dorsal-fin rays ii,6-7; anal-fin rays i,5; pectoral-fin rays i,6; pelvic-fin rays i,5 (Ref. 86681).
