This monkey is known only from Fanjingshan in Guizhou, China. Its blue face and chestnut-colored band across the chest are noted features.
The facial skin is blue, with pale pink above the eyes and around the mouth, and light gray fur borders the face. Males are larger and more brightly colored than females.
A study of winter diet found plant foods as well as insects and fungi; tree buds and shrubs were among the important plant foods.
