Beni Titi (Callicebus olallae)
The dental formula is 2:1:3:3 on both the upper and lower jaws (Ankel-Simons, 2000). The tail of the Beni titi is not prehensile. The forehead of the Beni titi is reddish brown agouti and the face is framed with blackish colored fur (Hershkovitz, 1990). The outer surface of the limbs is reddish brown (Hershkovitz, 1990). The back and sides are orange in coloration (Hershkovitz, 1990). The tail is dark agouti in color (Hershkovitz, 1990). The ears have whitish ear tufts in this species (Hershkovitz, 1990).
The Beni titi is found in the country of Bolivia (Hershkovitz, 1990). This is only known to occur in the upper Rio Beni drainage basin, Beni, Bolivia (Hershkovitz, 1990). This species lives in lowland forests up to 200 meters in elevation (Rowe, 1996).
The Beni titi is a diurnal and an arboreal species.
The Beni titi moves through the understory of the forest quadrupedally as well as by leaping (Fleagle, 1988).
tail-entwining: This is used to reinforce bonds amongst pairs. This is where two individuals are sitting and have their tails wrapped around each other's.
The Beni titi gives birth to a single offspring.
