|Scientific Name:||Callicebus lugens|
|Species Authority:||(Humboldt, 1811)|
|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 C. torquatus group contains C. torquatus, C. lugens, C. lucifer, C. purinus, C. regulus and C. medemi.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Veiga. L. M. & Palacios, E.|
|Reviewer(s):||Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)|
This species is listed as Least Concern due to a relatively large range in a remote part of the Amazon, occurrence in protected areas, and because there is no evidence of a decline that would warrant listing in a threatened category.
|Range Description:||This species has the largest range of the Callicebus torquatus group, occurring between the Rios Branco and Negro rivers in Brazil stretching as far north as the Rio Orinoco in Venezuela and the upper Caquetá in Colombia. Occurs in eastern Colombia in the departments of Vichada, Meta east of the Río Ariari, Guainiá, Guaviare, Vaupés, and Caquetá east of the Río Caguán, between the Río Tomo in the north and Río Caguán-Caquetá in the south; in southern Venezuela, in the state of Amazonas south of the Río Ventuari, and state of Bolívar between the Ríos Caura, Caroni, and Orinoco; and bordering parts of north-western Brazil, in Amazonas state north of the Rios Uaupés-Negro, and the state of Roraima west of the Rio Branco, north as far as the foothills of Mount Roraima (personal observations by M.G.M. van Roosmalen) (van Roosmalen et al. 2002). Casado et al. (2007) report that this species occurs south of the Rio Negro, in the municipality of Barcelos and therefore possibly sympatric with C. torquatus.|
