Etymology: Astyanax: The name of Astyanax, Hector´s son in the Greek mythology (Ref. 45335); lorien: 'lorien', i.e., from Quenya language, meaning dream land, used as an allusion to the beautiful place on the Chapada Diamantina inhabited by the species (Ref. 129195).
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.
