Recent molecular study indicated that this species (including species previously lumped with it) and C. loricatus are sisters, and that they are, together, sister to all other members of this genus#R. Hitherto present species considered conspecific with C. occidentalis and C. tinnunculus, but differs from former in having black collar and mantle (3), uniformly tawny-rufous vs buff-and-black-barred belly to vent (3), plain vs black-barred mantle, back, flight-feathers and tail (2), and paler head (ns), also hybrid zone in NE Brazil (at least 1); differs from C. tinnunculus in several obvious characters, e.g. almost complete absence of barring above and below. Form pieterroyensi (from E Pará, including Marajó I, and W Maranhão)#R is synonymized with torquatus, but may merit further examination. Currently treated as monotypic.
