Bryconalestes leuciscus (Günther, 1867)

Alestes leuciscus Günther, 1867:114 [5]. Type locality: West Africa (purchased of a dealer). [Boulenger (1909a) gave “Niger” as the type locality which was followed by Paugy (1986)]. Syntypes: BMNH 1865.1.20.16–17 (2).

Alestes (Brachyalestes) senegalensis Steindachner, 1870:545 [13], Pl. 2 (fig. 2). Type locality: Senegal. Syntypes: (many) BMNH 1891.5.26.17–18 (2); NMW 13375– 432 (58), 14222–26 (5), 66741 (2), 66774 to 66788 (4, 4, 2, 7, 5, 2, 4, 5, 4, 3, 3, 7, 4, 4, 5), 66790 to 66816 (4, 4, 4, 2, 4, 4, 4, 4, 4, 4, 2, 4, 4, 2, 5, 4, 3, 3, 4, 4, 4, 4, 4, 5, 2, 4, 120), 66824 (5), 67146 to 67147 (3, 10), 69610 (182), 75895 (5); ZMH 1799 (1), 1800 (1). The name Alestes nurse senegalensis proposed by Holly 1928 was not described as a new species, but is a new combination of an existing name [ Alestes (Brachyalestes) senegalensis Steindachner, 1870 ]. After examination of the type specimens of Alestes (Brachyalestes) senegalensis, Holly (1928b) placed it as a subspecies of Alestes nurse Rüppell, 1832 , an action which was erroneously treated as the description of a new subspecies by Paugy (1984).

Alestes nurse albolineatus Holly, 1928a:312 , fig. 1. Type locality: Senegal. Syntypes: NMW 13113–13133 (21); NMW 13134–13135 (2). [ NMW 13113–13133 (21) is indicated as “Cotype” on the original label and NMW 13134–13135 (2) is indicated as “Type” on the original label. The original publication mentioned 23 specimens, so all are syntypes. Also see Bogutskaya et al. (2022)].

Alestes nigrilineatus Svensson, 1933:53 , Pl. 2 (fig. 1). Type locality: swamps during rainy season, Gambia River , British West Africa. [ Gambia]. Syntypes: (4) NRM 10222 (3). [According to the original description 4 specimens were collected, but only 3 are registered at the NRM. At least one specimen is stated to be collected from another locality (i.e., Faraba creek) on 1 August 1931].

Distribution: 505, 506, 507, 508, 509, 516 (RMCA fish collection; Paugy, 1986; Paugy, 2003).
