Max length : 47.0 cm NG mâle / non sexé; (Ref. 43912)
Épines dorsales (Total) : 1. Diagnosis: adipose fin always present; anterior two nostrils closer to each other or almost at same distance from each other than posterior ones; inner mandibular barbel very slender, rudimentary or absent (sometimes only present on one side of head), if present never reaching beyond anterior eye border; eyes very small (especially in large specimens: negative allometry), 12.0-23.3% HL; snout reaching beyond lower jaw; inner side of pectoral spine feebly serrated; pelvic fin base slightly advanced in comparison with other related species, situated at same level as origin of dorsal fin base (Ref. 43912).
Oviparous, eggs are unguarded (Ref. 205). Might be a species adapted to rapids (Ref. 43912). Max. recorded SL 36.7 cm (Ref. 43912).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [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.
93245).
Niveau trophique (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref.
120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Assuming fec > 10,000).
Fishing Vulnerability (Ref.
59153): Low vulnerability (22 of 100).
