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.
