It was formally described in 2002 by Marc van Roosmalen and Russell Mittermeier, and named after Prince Bernard of the Netherlands. Locals were shown a photograph of the monkey and asked if they knew of its whereabouts, it was referred to as a "Zog-Zog". This titi has dark orange sideburns and chest, a reddish-brown back, and a black tail with a white tip. It is about 94 centimeters (37 in) in length, although
Collared titi is found west of the Río Purús to the Yavarí River. The collared titi is seen most frequently in well-developed, tall forest with a closed canopy, usually over terra firme, but not exclusively so. The species also enters extensive várzea forest, especially if the forest is tall and well-developed. Such várzea forest contrasts with the habitat needs of the coppery titi, which also uses várzea forest and more commonly so. But the coppery titi survives in low, vine-covered, "poor" forest where the collared titi is rarely found. It is also known from some gallery forest, north of the Vichada River,
