Africa: Cuanza River in Angola (Ref. 52193, 128501), also Cunene, Okavango, upper Zambezi, Buzi and Pungwe rivers, and an isolated population occurs in the Ruo River (lower Zambezi system) in Malawi (Ref. 52193). In the Congo basin known from the Kwango in Angola (Ref. 11970). Possibly also in the Inkisi River (lower Congo) (Ref. 12818, 120641), Lufira and Luwombwa rivers (upper Congo basin) (Ref. 12818) but these need confirmation.

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 18 - 19; Spine anali: 0; Raggi anali molli: 24 - 26. Diagnosis: dorsal fin origin nearer caudal fin base than tip of snout; origin of dorsal fin behind origin of anal fin; dorsal fin shorter than anal fin; chin (mental swelling) present but feebly developed; dorsal fin with 19 rays, anal fin with 24-26 rays (Ref. 52193).

Biologia     Glossario (es. epibenthic)

Found in rocky habitats in flowing waters (Ref. 7248, 52193). Feeds on small aquatic invertebrates (Ref. 7248, 52193) such as insect larvae (Ref. 7248).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00251 - 0.01261), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.40 se; based on food items.
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
