Formerly thought to be closely related to A. collaris. Recent information on skeletal details indicates that present species does not even belong in genus Accipiter#R, a finding further supported by genetic data#R; it appears not to be close to any other accipitrid group. It has been recommended that it be transferred to its own genus, in which case the name Hieraspiza has been suggested as available#R, but type species of that genus is A. virgatus#R, as nominated by genus author, Kaup, prior#R to G. R. Gray’s subsequent (and therefore irrelevant) selection of “Falco tinus” (a synonym of present species); thus, another valid genus name is required. Two subspecies recognized.
