Scientific Name:

Callicebus bernhardi

Species Authority:

M. van Roosmalen, T. van Roosmalen & R.A. Mittermeier, 2002

Common Name/s:

English

–

Prince Bernhard’s Titi Monkey, Prince Bernhard's Titi Monkey

Taxonomic Notes:

Kobayashi and Langguth (1999) and van Roosmalen et al. (2002) recognize five species groups – cupreus, donacophilus, moloch, personatus and torquatus. According to van Roosmalen et al. (2002), the moloch group consists of Callicebus baptista, Callicebus moloch, Callicebus brunneus, Callicebus cinerascens, Callicebus hoffmannsi and the newly described Callicebus bernhardi.

Assessment Information [top]

Red List Category & Criteria:

Least Concern ver 3.1

Year Published:

2008

Assessor/s:

Veiga, L.M.

Reviewer/s:

Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)

Justification:
This species is listed as Least Concern due to having a relatively large range in a region that is still secure from anthropogenic impact, and there is no evidence of any major threats resulting in a decline that would qualify the species for listing in a threatened category.

History:

2003

Least Concern (IUCN 2003)

Geographic Range [top]

Range Description:	This species is found between the Rios Tapajós and Madeira/Jiparaná. The ranges of Callicebus bernhardi, Callicebus cinerascens and Callicebus hoffmannsi may intergrade in some way in the region of the headwaters of the Rios Juruena, Aripuanã and Roosevelt. Callicebus bernhardi occurs in the interfluvium delineated by the Rios Madeira-Jiparaná and Rios Aripuanã-Roosevelt, in the states of Amazonas and Rondônia, Brazil (van Roosmalen et al. 2002). There is a possible sighting in a 50-ha reserve in Alta Floresta in Mato Grosso State, Brazil (Stepp 2003).

Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	There are no data available on the ecology of this species. Titi monkeys (Callicebus spp.) are known to occur in a wide range of habitats, although some species exhibit habitat preferences, for example C. lucifer is reported to prefer white-sand forests (E. Heymann pers. comm. 2008), and C. donacophilus drier forests (Ferrari et al. 2000; R. Wallace pers. comm.). Members of the C. moloch and C. cupreus groups are considered tolerant of habitat disturbance caused by human activity or seasonal flooding (van Roosmalen et al. 2002). The diet of titis comprises mainly fruit pulp, leaves, insects and seeds. They form small, pair-bonded, territorial groups and are considered monogamous. They have small home (1.5-30 km) and day ranges (0.5-1.5 km).
Systems:	Terrestrial
