Erythrotriorchis

Erythrotriorchis is a genus of bird of prey in the family Accipitridae. It contains the following species:
 * Chestnut-shouldered goshawk (Erythrotriorchis buergersi)
 * Red goshawk (Erythrotriorchis radiatus)

Etymology
"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.

Taxonomy
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.
