Scientific Name: Aotus azarae ssp. azarae
Species Authority: (Humboldt, 1811)
Parent Species:
Common Name(s):
English Azara’s Night Monkey
Spanish Mono Nocturno
Taxonomic Notes: It is doubtful that the current taxonomy provides a true picture of the diversity of the genus Aotus. Ruiz-Herrera et al. (2005) reported that cytogenetic studies have characterized 18 different karyotypes with diploid numbers ranging from 46 to 58 chromosomes. The taxonomy of the night monkeys essentially follows the revision by Hershkovitz (1983), with some modifications for the Colombian and Central American forms.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Fernandez-Duque, E., Wallace, R.B. & Rylands, A.B.
Reviewer(s): Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
This subspecies is listed as Least Concern because it is not believed to be declining at a rate that would warrant listing in a threatened category. Due to its small size, this subspecies is rarely hunted and so the only potential major threat is habitat loss which occurs at relatively low rates.
Previously published Red List assessments:
2003 Least Concern (LC)
1996 Lower Risk/least concern (LR/lc)
