Dorsale stekels (totaal) : 0; Anale stekels: 0; Anale zachte stralen: 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
Fylogenetische diversiteitsindex (Ref.
82804): PD
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.
93245).
Trofisch niveau (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
