Previously thought possibly closest to Phalcoboenus chimango, which was then placed in present genus, and both species sometimes included in Polyborus (= Caracara); recent molecular study, however, indicates that the two are not close relatives, and not even congeners#R. Described form paludivaga (from Suriname) is a synonym of cordata, and strigilata (R Xingu, in E Brazil) of nominate. Two subspecies recognized.
