Graells's tamarin

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]
