Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 7; Espinas anales: 0; Radios blandos anales: 11 - 12. Body elongate and compressed; snout broad and spatulate. Barbels extend posteriorly to pelvic fins or beyond to anal fin. Dorsal spine weakly serrated on its posterior edge; adipose fin base short, about as long as the rayed dorsal fin base. Color is brownish-gray on back, silvery on flanks and belly. A dark well-defined spot is on the adipose dorsal fin.
Body shape (shape guide): elongated; Cross section: oval.
