Etymology
The new genus name Robaloscion is derived from the local Peruvian name “robalo” in use for fishes of the species Sciaena wieneri, and “scion”, a root commonly used since Gill (1861) in sciaenid generic names for its resemblance to Sciaena (drum). English common name proposed: robalo drum; French name: courbine de Wiener; Spanish name: robalo peruano.
