Justification:

Ateles hybridus was assessed as Endangered in 1996. It is now reassessed as Critically Endangered.

Both Ateles hybridus hybridus and Ateles hybridus brunneus are considered to be at extreme risk in Colombia. It is important to underline the precarious condition of these two taxa, one of which (A. h. brunneus) has not been widely recognized by many and is a Colombian endemic from a recognized dispersal center (the Nechí). Censuses are required for a better understanding of the status of Ateles hybridus, and local populations need to be clearly identified and actively managed; a situation that does not exist at this time, even in the protected areas where A. h. hybridus is known to occur. The habitat of A. h. hybridus is extremely fragmented, and there may be few populations of an adequate size to be viable in the mid-to long-term (Defler et al. 2003).
