The lesula[1] (Cercopithecus lomamiensis) is a species of Old-World monkey occurring in the Lomami Basin of the Congo.
- Slender, medium-sized Lesulas feature a strong color contrast in their coat pattern, with blonde fur along the upper chest, throat, and chin.
- Black fur covers the lower abdomen and ventral region, fading to silver-gray tones on the thigh’s proximal half.
- Amber fur grows at the proximal end of their long, thin tails, gradually darkening to black towards the tip.
- The fur on the shoulders and long front legs is black. Their face, ears, and eyelids are bare and range in color from pinkish gray to brown.
- Lesulas and its sister species, Cercopithecus hamlyni, are distinguished from all other species in the genus Cercopithecus by their vertical nasal stripe, skull shape, and facial mane.
