The golden-mantled tamarin[1] (Leontocebus tripartius) is native to South America.
- It is found in Peru and Ecuador, especially in the upper Amazon (lowlands), east of the Andes in Ecuador, and northeastern Peru, between the Curaray River and the Napo River in Peru.
- This tamarin measures 218 to 240 mm from the tip of the nose to the beginning of the tail and has a tail length of 316 to 341 mm.
- The length of its ear is 31 to 32 mm. The head is black, with a continuous collar of black hairs below the throat.
- The muzzle and sometimes the face is pure white, and the neck has a light gold collar with cream fur on the back that contrasts sharply with the black crown.
- Its underside is orange. The long tail is non-prehensile, like all tamarins, and the large eyes are forward-facing.
