Abstract

The binomen Aotus jorgehernandezi Defler & Bueno, 2007 was erected for a species of night monkey diagnosed on the basis of karyomorphic differences. The type locality of A. jorgehernandezi is unknown, as the original description was based on a single specimen found in captivity in the Andean region of Colombia but presumed to be native to Los Nevados National Natural Park, located on the border between the departments of Quindío and Risaralda, in the Central Cordillera of Colombia. Since the description of this species, the binomen has been controversial as the holotype is lost, and as no additional specimens referred to this species are yet known. Here, we evaluate the nomenclatural validity of A. jorgehernandezi and the taxonomic traits used for its description, comparing it to other Aotus species from Colombia. Although the binomen A. jorgehernandezi is nomenclaturally available, taxonomic traits including the karyotype information strongly suggest that it is a junior synonym of A. brumbacki Hershkovitz, 1983, which has a cis-Andean distribution in Colombia.
