Erythrotriorchis is a genus of bird of prey in the Accipitridae family. It contains the following species:Chestnut-shouldered goshawk (Erythrotriorchis buergersi)
Red goshawk (Erythrotriorchis radiatus)
"Erythro-" is from a Greek word for "red", and "triorchis" meant a kind of hawk thought to have three testicles. For further details see Eutriorchis.
Latham described the red goshawk as Falco radiatus in 1801. Sharpe defined Erythrotriorchis in 1875 as a new monotypic genus for Falco radiatus.
Peters also included E. doriae in the genus, though Doria's goshawk is now classified separately as Megatriorchis doriae.
