Comments: Reported from the southern Congo River basin (Ref. 120641) at Bange Ngola (Kwango River system, Kasai River drainage) (Ref. 1878). Reports of the species from westward flowing basins in Ref. 11970 is based on Ref. 1878, but the latter only reports the species from the Kwango (Congo basin; see above). Questionably present in the Zambezi (Ref. 120641). Report from the "Cuanza (Atlantic coastal)" (Ref. 120641) probably refers to the Cuanzan drainage basin or Cuanza Ichthyological Province, including various Angolan coastal basins, and not (only) the Cuanza river basin. Also Ref. 3022, 3565, 83360, 83772.

Africa: Kwango drainage (middle Congo River basin) in Angola (Ref. 1878). Also reported from the Kunene and (upper) Zambezi systems (Ref. 13332), although presence in the latter is questionable in Ref. 120641. Presence in the Okavango (Ref. 13332) and southern Kasai (Ref. 45616) uncertain, although considered present in the southern Congo basin in Angola in Ref. 120641.

Diagnosis: body height less than head length (Ref. 3022), the latter 5.5-6 times in total length (Ref. 1878, 3022). Eye lateral, well visible from below (Ref. 1878), its diameter 3-3.66 times in head length (Ref. 1878, 3022). Dorsal fin origin behind pelvic fins (Ref. 1878, 3022). In males, snout with spine-like tubercles (Ref. 1878, 83772). Ventral profile of lower jaw slightly ventrally curved, except in the middle where it is more or less dorsally curved; more than 100 scales on lateral line; blackish grey band from the back of the head to the caudal fin (Ref. 83772). Lateral line origin curving dorsally above opercular organ, the latter not overlying the anterior lateral line (Ref. 88971). Black spot at base of pelvic and pectoral fins; 2 black spots at base of anal fin (Ref. 3022, 83772). Blackish brown spots just above and below lateral line (Ref. 83772).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
