Etymology: Astyanax: The name of Astyanax, Hector´s son in the Greek mythology (Ref. 45335).
Eponymy: Astyanax was the son of Hector in Greek mythology. See Homer’s Iliad for details. The reasoning for its use for a genus of characins is not explained. (Ref. 128868), visit book page.

Issue
Ruiz et al., 2018 (Ref. 119406:19) revision's placement of Astyanacinus multidens Pearson, 1924 to the genus Astyanax relegates it to the status of a junior secondary homonym of Astyanax multidens Eigenmann, 1908. Thus, it is proposed that Astyanax bopiensis nom. nov. replacement name, is used following rules established in Article 59 of the International Code of Zoological Nomenclature (ICZN 1999).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00382 - 0.01577), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 2.8 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
