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. D Bourget was a French naturalist who was resident in Rio de Janeiro. He was a member of the Thayer Expedition to Brazil (1865–1866), engaged by Agassiz as a collector and preparator. He collected the holotype. (Ref. 128868), visit book page.
