The red-mantled saddle-back tamarin was formerly considered to be a subspecies of the brown-mantled tamarin, L. fuscicollis. It lives in Ecuador and Peru and its type locality is in Peru, near the confluence of the Amazon River and the Napo River.
The red-mantled saddle-back tamarin has a head and body length of between 220 millimetres (8.7 in) and 270 millimetres (11 in) with a tail length between 275 millimetres (10.8 in) and 330 millimetres (13 in) long. It weighs between 350 grams (12 oz) and 400 grams (14 oz).
