Africa: Ouémé basin (Benin) (Ref. 57415, 81678) up to the Ntem (Cameroon) (Ref. 81678), including the Lake Chad basin (Ref. 57415). Also known from Bioko Island (formerly Fernando Poo) in Equatorial Guinea (Ref. 81678). Reported from the middle Congo River basin (Ref. 6060, 46252), but this is questionable and unconfirmed in Ref. 57415 or 81678.
非洲: 在喀麥隆與剛果河中游流域的 Ntem。 除了尼日以外的貝南與大多數的大西洋的流域也已知來自 Oueme 河。 (參考文獻 7394) 這種的屬鑑定是試驗性的, 未決定的標本的有效為解剖的分析。

背棘 (总数) : 24 - 33; 背的软条 (总数) : 93 - 143; 臀鳍软条: 90 - 140; 脊椎骨: 95 - 118. Diagnosis: distance from tip of snout to last externally visible dorsal spine relatively short, 43.2-57.9% SL, decreasing with size (Ref. 57415, 81678). Postanal length relatively long, 44.1-58.3, increasing with size (Ref. 57415, 81678), comparable to or longer than preanal length, 40.0-51.8% SL (m=46.6)(Ref. 57415, 81678). Distance from tip of snout to last externally visible anal spine relatively short, 44.3-57.3 SL, decreasing with size (Ref. 57415, 81678). 1st dorsal spine situated clearly posterior to posterior edge of pectoral fin (Ref. 57415), distance from posterior edge of pectoral fin to origin of first dorsal spine 8.9-89.3% HL (Ref. 57415, 81678). Gill opening small, its distance to dorsal pectoral fin base relatively long, 8.3-14.9% HL (mean 11.5%); 23+1 to 32+1 (median 27+1) dorsal spines (Ref. 81678). Distance from anterior border of snout to first anal spine 42.1-53.5% SL (m=48.2), decreasing with size (Ref. 57415).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00257 (0.00122 - 0.00544), b=2.97 (2.79 - 3.15), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100).
