VILLOTA, Johana et al. Distribution update and natural history of Plecturocebus caquetensis (Mammalia: Pitheciidae) in Colombia. Biota colombiana [online]. 2022, vol.23, n.1, e213.  Epub Feb 18, 2022. ISSN 0124-5376.  https://doi.org/10.21068/2539200x.1007.

The Caquetá titi monkey, Plecturocebus caquetensis (Primates: Pitheciidae), is endemic to the Amazon foothills in the departments of Caquetá and Cauca, Colombia. Being a species recently described, the information on its distribution and natural history is still scarce. We present a distribution update and observations on its natural history and ecological relationships in the Department of Cauca. We obtained 129 occurrences in Caquetá (n=75) and Cauca (n=54), 51 and 31 of them, respectively, representing new records for each department. The extension of occurrence (EOO) and area of occupancy (AOO) were 3741 km2 and 196 km2, respectively. Among the natural history observations, P. caquetensis occurred mainly in the edges of seasonally flooded forests with bamboo plants (Guadua sp.). The diurnal behavior included vocalization, locomotion, rest, play and feed. Ecological relationships of the species with birds, reptiles and mammals includes predation events by boas and birds. Furthermore, ecological observations about the consumption of bamboo petioles and the use of Vochisia sp. trees as nesting site is provided. We suggest exploring the presence of P. caquetensis in the "Serranía de los Churumbelos Auka-Wa- si" protected area and the creation of conservation plans with the communities inhabiting the distribution area.
