Can be further diagnosed by the following combination of characters unique within the Loricariidae: naked snout with no tentacles; absence of nuchal plate; absence of first dorsal-fin spinelet; absence of adipose fin; three median unpaired plates in position of adipose fin; dentary wide with anguloarticular slightly projected dorsolaterally; lateral anterior process of the basipterygia narrow, almost in contact with the medial anterior process of the basipterygia at midline (Ref. 93320).Description: Lateral-line plates 24- 25. Anal fin absent to inconspicuous; when present anal fin with 1, 2 or 3 rays, all unbranched (Ref. 93320).
