It is found in Ivory Coast, Ghana, Guinea, Liberia, Sierra Leone, Togo, Guinea-Bissau, and possibly Senegal.

The crown, back, outer side of the limbs and upper surface of the tail are olive-green or khaki.

Its range includes Guinea-Bissau, Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana and Togo, and it has also been recorded in southeastern Senegal.

[3] The lesser spot-nosed monkey is diurnal, arboreal and cryptic; it moves through the forest cautiously, seldom climbing to the high canopy but mostly frequenting the understorey layers and lianas.

It feeds on leaves, fruit, flowers and insects, gathering its food and storing it in cheek pouches; when these are full, they are prominent, its white throat resembling a snowball.
