Andean Titi (Callicebus oenanthe)


MORPHOLOGY:
The dental formula is 2:1:3:3 on both the upper and lower jaws (Ankel-Simons, 2000). The tail of the Andean titi is not prehensile. The forehead is colored buffy or whitish with the color continuing down and bordering the face (Hershkovitz, 1990). The sideburns and outer surface of the limbs are agouti in coloration (Hershkovitz, 1990). The inner surface of the limbs, the chest, and the belly are orange (Hershkovitz, 1990). The lumber region and the legs are reddish-brown (Aquino and Encarnacion, 1994). The tail of this species is dark brown agouti (Hershkovitz, 1990). The body pelage is thick in the Andean titi (Hershkovitz, 1990).

RANGE:
The Andean titi is found in the country of Peru (Hershkovitz, 1990). This species is only found in the upper Rio Mayo valley in the department of San Martin (Hershkovitz, 1990). The Andean titi occurs at an altitudinal range of 750-950 meters (Hershkovitz, 1990). This species lives in the cloud forests (Aquino and Encarnacion, 1994).

The Andean titi is a diurnal and an arboreal species.
