Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 1; Dorsal soft rays (total): 7. Distinguished from other species in this genus in having the following set of characters: 1-4 weakly developed serrations, distally located on the anterior part of the dorsal spine (vs. entirely well serrated); mandibular teeth 12-19 (vs. at least 23); membrane broad; i.e., proximally at least as brad as barbel thread, on the proximal 2/3 of the maxillary barbel (vs. none or very weakly developed); striking color pattern, black background with whitish irregularly shaped lines and dots (Ref. 78701).
Specimens have been caught in the Dola River (Gabon) at depth of 0.80 m above a sand/gravel substrate; water here was opaque, alkaline (pH 8.41) with high conductivity and with temperature of 24.0°C (Ref. 78701).

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=0.01175 (0.00468 - 0.02950), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 2.9 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
