The Rio Cesar capuchin monkey ( Cebus cesarae , syn .: C. albifrons pleei ) is a species of primate from the family of the capuchin-like that occurs in northern Colombia.
features
The Rio Cesar capuchin monkey reaches a head-trunk length of 35 to 40.7 cm and has a 42 to 50 cm long tail. Of all the capuchin monkeys from Venezuela and northern Colombia, it is the species with the lightest fur. The hair on the sides of the head, chin, throat, neck and around the ears is light beige-brown. The cap on the head is tobacco-colored or brown-orange. The back and the outside of the arms and legs are brown-orange and contrast with the light beige-brown, silvery white shimmering belly side. The top of the tail is cinnamon in color.

The Rio Cesar capuchin monkey is found in northern Colombia. The small distribution area includes the catchment area of the Río Cesar , a tributary of the Río Magdalena , and lies between the lower reaches of the Río Magdalena and the coastal mountains Sierra Nevada de Santa Marta .
Way of life
The Rio Cesar capuchin monkey lives in dry and semi-arid remains of deciduous forest, in gallery forests and mangroves up to heights of 500 meters (south and east of the Sierra Nevada de Santa Marta). The forests in its habitat have been largely cut down. Nutrition, reproduction and other behaviors have not yet been researched in detail.
Systematics
In 1949 the mammaloge Philip Hershkovitz described two new forms of monkey as subspecies of the white-fronted capuchin ( Cebus albifrons ), on the one hand the Rio Cesar capuchin monkey from the catchment area of the Rio Césare, on the other hand the Cebus albifrons pleei from the west bank of the Rio Magdalena at the base of the northern one Foothills of the Cordillera Central . The lineage of these two forms separated from the Colombian capuchin monkey ( Cebus versicolor ) 300,000 to 120,000 years ago. Since both are very similar, was Cebus albifrons pleei with the Rio Cesar Capuchin monkeys as synonymous . According to the priority rule in biological nomenclature , older names have priority over younger (later published) names. Since both appeared in the same issue of the "Proceedings of the United States National Museum", the number of pages had to suffice in this case to meet the priority rule; the description of Cebus albifrons cesarae is on page 356, that of Cebus albifrons pleei on page 360 In addition, Jean P. Boubli and research colleagues raised the Rio Cesar capuchin monkey to an independent species in 2012, which was adopted in the following year in the primate volume of the Handbook of the Mammals of the World and also by the IUCN .
Danger
As insufficient data are available, the IUCN does not provide any information about a potential threat to the Rio Cesar capuchin monkey (data deficient).
