Issue
Paugy & Shaefer (2007: Ref. 80290) put the validity of the species in doubt as being a morphotype of Brycinus macrolepidotus Valenciennes 1850. This requires confirmation most likely with genetics studies (Paugy, pers,comm., 21 Mar. 2013). This species is placed in the genus Alestes Müller & Troschel, 1844 in Eschmeyer (CofF ver.Feb. 2013: Ref. 93002) following Paugy (1984: Ref. 5331). Treated here under the genus Brycinus following Paugy (1986: Ref. 42019).
