The dental formula is 2:1:3:3 on both the upper and lower jaws (Ankel-Simons, 2000). The tail of Hoffmann's titi is not prehensile. Adult males can have a mass of around 1.09 kilograms and females can have a mass of around 1.03 kilograms (Smith and Jungers, 1997).

This species has two subspecies each having their own pelage coloration:

RANGE:
Hoffmann's titi is found in the country of Brazil (Hershkovitz, 1990). This species in forests found in swamps and on river's edges (Rowe, 1996).

Each subspecies has their own distinct ranges:

ECOLOGY:
Hoffmann's titi is a diurnal and an arboreal species.

LOCOMOTION:

SOCIAL BEHAVIOR:

VOCAL COMMUNICATION:

OLFACTORY COMMUNICATION:

VISUAL COMMUNICATION:

TACTILE COMMUNICATION:
