Africa: Senegal (Ref. 57413, 81660) to the Kunene River in Namibia (Ref. 81660). In Lower Guinea found in lower courses of most rivers, though not apparently collected from southern Gabon (Ref. 81660).
Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 12.3 cm TL macho/indeterminado; (Ref. 57413)
Espinhos dorsais (total) : 6 - 7; Raios dorsais (total) : 7 - 8; Espinhos anais: 1; Raios anais : 7 - 8. Diagnosis: 40-54 (usually 45-49) scales in longitudinal series on flanks (Ref. 57413, 81660), and 2-4 scales on caudal fin base (Ref. 57413). 11-18 (usually 13-514) scales in rearward transverse series (Ref. 57413, 81660). Body pigmentation usually pale/rusty brown, with rows of dark spots in longitudinal series dorsal to lateral midline (Ref. 57413). Prominent dark spot on dorsal part of pectoral fin base (Ref. 57413, 81660), if specimen is very dark spot may not be highly contrasted but is still distinct (Ref. 81660). Sensory papillae on upper rear field of opercle form a single arching row (Ref. 81660).
Occurs in brackish environments and freshwaters of coastal rivers (Ref. 57413). Maximum reported standard length 97 mm (Ref. 81660).
