Short description
Morfología | Morfometría
Espinas dorsales (total): 1; Radios blandos dorsales (total): 8-9; Radios blandos anales: 11. Head smooth above; snout broadly rounded; band of premaxillary teeth 6 times as long as broad, close to and nearly as broad as the crescentic band of vomerine teeth; maxillary barbel 2.25 times head length, reaching beyond pelvic fins; nasal barbel 0.4 times head length; inner mandibulary barbel 0.43 times head length; outer mandibulary barbel 0.86 times head length; occipital processus narrow and short, widely separated from the first interneural bone; longest branched ray of dorsal fin 0.71 times head length; dorsal spine very weak; adipose fin 4 times longer than high, much longer than the base of the dorsal fin; caudal fin deeply forked, both lobes with long filaments; pectoral spine weak with the outer half articulated (Ref. 52141).
Coloration: brown above with irregularly scattered small black dots which are most numerous on the caudal and adipose fin, but are also seen on the back and sides; no dots below lateral line; whitish below (Ref. 52141).

50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
