Africa: Nigeria to Cameroon (Ref. 57127), possibly from coastal rivers in Togo (Ref. 78218). Known from the rivers Ogun (Ref. 13331), lower Niger (Ref. 13331, 57127), Kwa-Ibo and Cross in Nigeria (Ref. 57127), and the Wouri, Sanaga and Nyong in Cameroon (Ref. 7351, 43912, 51193). Report from Ogowe (Ref. 43912) represents S. laticeps (Ref. 81643). Report from the Congo River basin (Ref. 51193) not confirmed in Ref. 43912, 78218 or 81643.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00264 - 0.01256), b=3.02 (2.83 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Assuming fec > 10,000).
Vulnerability (Ref. 59153):  Low vulnerability (15 of 100) .
Price category (Ref. 80766):   Unknown.
