Graells's tamarin, Leontocebus nigricollis graellsi, is a subspecies of the black-mantled tamarin from the northwestern Amazon in southeastern Colombia, eastern Ecuador and northeastern Peru. [3] [4] It differs from other black-mantled tamarins in having a dull olive-brown (no reddish-orange) lower back, rump and thighs. [5] [6] However, molecular genetic analysis does not support treating Graell's tamarin as a separate species from the black-mantled tamarin. [3]
