Saguinus nigricollis ssp. graellsi
|Scientific Name:||Saguinus nigricollis ssp. graellsi (Jiménez de la Espada, 1870)|
|Taxonomic Notes:||The taxonomy of Saguinus nigricollis follows Hershkovitz (1982).
Saguinus n. graellsi is listed as a full species by Hernández-Camacho and Cooper (1976) and Defler (1994), on the basis that it is sympatric with a population of S. nigricollis in the region of Puerto Leguízamo in southern Colombia. Hernández-Camacho and Defler (1991) listed it as a subspecies of S. nigricollis, agreeing with Hershkovitz (1977). It was listed as a distinct species by Groves (2001, 2005) following the supposition of its sympatry with S. n. nigricollis. However, Defler (2003, 2004) has indicated that the occurrence of S. n. nigricollis north of the Rio Putumayo is doubtful.

|Reviewer(s):||Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)|
This subspecies is listed as Near Threatened because the region where this species occurs has one of the highest rates of deforestation in the western Amazon, and it is estimated that the population may experience a decline in the region of 20-25% over three generations (18 years) due to previous and ongoing deforestation of the Amazon forests where it is found. Almost qualifies as threatened under criterion A4c.
