French: Titi du Caqueta / German: Caqueta-Springaffe / Spanish: Titi del Caqueta
Other common names: Caqueta Titi Monkey
Taxonomy. Callicebus caquetensis Defler et al., 2010,
Vereda El Jardin, municipality of Puerto Milan, department of Caqueta, Colombia (01° 08’ 24-61” N, 75° 32 34-04” W).
C. caquetensis is a member of the C. cupreus species group. Monotypic.
Distribution. SW Colombia (Caqueta Department); known only from eleven sites between the rios Caqueta and Orteguaza, which appear to define the S, E, and N limits of the distribution, with the foothills of the Andes to the W.
Descriptive notes. Head-body length of the holotype, a juvenile female, was 35 cm; no other measurements available. Male and female Caqueta Titis are equal in size and coloration. Pelage of back, arms, and legs down to elbows and knees is grayish-brown agouti. Tail is grayish-agouti, fading to white and black agouti in the terminal onethird. Ventral surfaces of body, arms, and legs are sparsely haired and chestnutred, which extends to dorsal surfaces of arms and legs, as far as elbows and knees, and reddish coloration extends to ventral portions of neck and cheeks, giving the appearance of a distinct red beard. Facial skin is relatively dark, and forehead is white and gray agouti, with white-tipped hairs. Forehead band is buffy-orange and black, with whitetipped hairs replaced by bufty-orange.
Habitat. [Lowland Amazon rainforest at elevations of 190-260 m. The Caqueta Titi is found mainly in disturbed terra firma forest but also in low, swampy habitats.
Food and Feeding. There is no information available for this species.
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. Thirteen groups of Caqueta Titis observed in the wild contained 3-6 individuals, and all contained only a single adult male and female (breeding pair).
Status and Conservation. CITES Appendix II. Classified as Critically Endangered on The IUCN Red List. In addition to its relatively small range, the Caqueta Tit is threatened by widespread deforestation, which has removed more than 50% of the natural vegetation and reduced available habitat to small, isolated forest fragments. In addition to deforestation, ongoing threats may include hunting and fumigation/defoliation ofillegal crops by government forces. The Caqueta Titi is not known to occur in any protected areas.
