BRYCONALESTES Hoedeman, 1951

G Boden, E Derijst

Alestobrycon Hoedeman, 1951:3 (in key). Type species: Alestes intermedius Boulenger, 1903 . Type by original designation. Gender: Masculine.

Bryconalestes Hoedeman, 1951:4 (in key). Type species: Brachyalestes longipinnis Günther, 1864 . Type by original designation. Gender: Masculine.

Remarks: This genus corresponds to the ‘ Brycinus longipinnis ’ group as defined by Paugy (1986), which was placed in the genus Bryconalestes by Zanata, Vari (2005). They explicitly mention the species B. longipinnis , B. derhami and B. intermedius as belonging to this group, of which the last one is also the type species of the genus Alestobrycon (not mentioned by Zanata, Vari (2005)). Both genera were described by Hoedeman (1951) in a key in the same publication. Alestobrycon is indicated as a new genus with type species Alestes intermedius Boulenger, 1903 on page 3. Bryconalestes is indicated as a new genus with type species Brachyalestes longipinnis Günther, 1864 on page 4. Zanata, Vari (2005) have placed both species in the same group for which they utilise the genus Bryconalestes . The revalidation of Bryconalestes by Zanata, Vari (2005) cannot be regarded as an act of the first reviser, because they did not cite Alestobrycon , or mentioned any act of selection (ICZN,1999: Art. 24.2.1. Statement of the Principle of the First Reviser. When the precedence between names or nomenclatural acts cannot be objectively determined, the precedence is fixed by the action of the first author citing in a published work those names or acts and selecting from them; this author is termed the “First Reviser”). Here we act as the first reviser and treat Bryconalestes as a valid genus.

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).
