Taxonomy. Callicebus aureipalatii Wallace et al., 2006 ,

Roco Roco Camp (14° 37°30” S, 67°43” 06” W) on the Rio Hondo in Madidi National Park, department of La Paz, Bolivia.

C. aureipalatii is a member of the C. moloch species group. Monotypic.

Distribution. SE Peru (Puno and Madre de Dios departments) and W Bolivia (appears to be limited to the E by the Rio Beni and to the S by the foothills of the Andes); it ranges W across the Rio Heath to the Rio Tambopata, but the N and W limits are unclear.

Descriptive notes. Head—body 29-3 cm (males) and 32 cm (females), tail 52-4 cm (males) and 48 cm (females); weight 1000 g (males) and 900 g (females). Male and female Madidi Titis are indistinguishable in size and coloration. Head and body are uniformly light brown, with agouti-banded hairs that are gray-brown at the base, fading to a light brown tip, as far as elbows and knees. Underparts are pale orange and sparsely haired, with hair density and orange coloration increasing to chest, throat, and especially sideburns. Forearms and lower legs are also orange. Tail is brown to black at its base, fading to a distinct white tip. Face is black.

Habitat. [Lowland Amazon rainforest at elevations of 100-500 m in the foothills of the Andes. The Madidi Titi appears to prefer relatively dense habitats with high densities of lianas.

Food and Feeding. Preliminary data from the type locality of the Madidi Titi indicate that it is relatively frugivorous, like othertitis.

Breeding. There is no specific information available for this species, but all titis form monogamous breeding pairs. The male provides parental care by carrying the single offspring.

Activity patterns. There is no information available for this species.

Movements, Home range and Social organization. Home ranges of two study groups of Madidi Titis were 17-25 ha.

Status and Conservation. CITES Appendix II. Classified as Least Concern on The [UCN Red List. The Madidi Titi is not under any immediate risk, but there is some hunting by indigenous communities and a number of potential threats from development projects (roads, oil exploration, and dams). It is found in Madidi National Park in Bolivia and Tambopata National Reserve and Bahuaja-Sonene National Park in Peru.
