Brycinus imberi (Peters, 1852)

Alestes imberi Peters, 1852:276 . Type locality: Mossambique. [ Peters (1852) gave a short description of Alestes imberi , without mentioning an exact locality. However , Peters (1868a) provided more details about the locality: “ Flumina Zambeze et Licuare ”. Mozambique]. Lectotype: ZMB 3574 . [Designated by Seegers (1996)].

Alestes fuchsii Boulenger, 1899b:83 , Pl. 36 (fig. 1). Type locality: Boma (rivière des crocodiles), Stanley-Pool (région des chutes), lac Léopold II et Monsembé, Congo. [ Democratic Republic of the Congo]. Syntypes: BMNH 1896.3.9.22– 23 (2); BMNH 1899.9 .26.94 (1); BMNH 1901.12.21.25–26 (2); RMCA 796 (1) ; RMCA 797 (1) ; RMCA 798 (1) ; RMCA 799 (1) . [It is clear that Boulenger (1899b) has seen the syntypes BMNH 1896.3.9.22–23 (2; River Congo, 50 miles south of Mangala [changed to Monsembé by Boulenger (1909)]) and BMNH 1901.12.21.25–26 (2; Monsembé) at the time of the description of Alestes fuchsii , because he mentioned specimens from Monsembé. However, they were not indicated as syntypes in Boulenger (1909), which was probably followed in later publications] .

Alestes lemairii Boulenger, 1899b:84 , Pl. 36 (fig. 2). Type locality: lac Moero , Congo. [ Democratic Republic of the Congo]. Syntypes: BMNH 1899.11 .27.97 (1), RMCA 221 (1).

Alestes fuchsii var. taeniata Pellegrin, 1903:328 . Type locality: Ouellé. [ Democratic Republic of the Congo]. Holotype: MNHN 1903-0291 .

Alestes bequaerti Boulenger, 1920a:148 . Type locality: Ituri , à Avakubi. [ Democratic Republic of the Congo]. Holotype: RMCA 14538 .

Alestes curtus Boulenger, 1920b:16 . Type locality: Avakubi , Congo belge. [Democratic Republic of the Congo]. Holotype: RMCA 7584 .

Distribution: 507, 512, 514, 515, 516, 517, 534, 535, 536, 537, 539, 540, 541, 542, 543, 544, 545, 546, 548, 549, 550, 551, 558, 559, 560, 561, 563, 564, 565, 576 (Boulenger, 1909a; Poll, 1953; Banister, Bailey, 1979; Paugy, 1986; Seegers, 1996; De Vos et al., 2001; Skelton, 2001; Paugy, 2003; Snoeks, 2004; Paugy, Schaefer, 2007; Marshall, 2011; Van Steenberge et al., 2014; Mbimbi Mayi Munene, Stiassny, 2011).

Remarks: Taxonomic uncertainties remain in Brycinus imberi , a widespread species that is morphological variable compared to other species in the genus. According to Paugy, Schaefer (2007) it is not present in the Lower Guinea Ichthyofaunal Province. According to Marshall (2011) the population that occurs in the coastal rivers of West Africa is likely to be a different species.
