Graells's tamarin

Subspecies of New World monkey

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. It differs from other black-mantled tamarins in having a dull olive-brown lower back, rump and thighs. However, molecular genetic analysis does not support treating Graell's tamarin as a separate species from the black-mantled tamarin.
