Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Épines anales: 0; Rayons mous anaux: 28 - 29. Snout fairly long, 4 times in head but less than eye diameter; maxilla short, tip nearly square, not quite reaching to articulation of lower jaw; lower gill rakers (not counted), about equal to eye diameter. Pectoral fin long, reaching halfway along pelvic fin; anal fin long, its origin below middle of dorsal fin base. An indistinct silver stripe along flank.
Presumably riverine or estuarine. More material and data needed.

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00253 - 0.01141), b=3.13 (2.96 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Niveau trophique (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref.

Fishing Vulnerability (Ref.
