The fecal sample of Ateles marginatus yielded DNA that was too degraded for successful long-range amplification, thus for this sample alone we amplified overlapping regions of mtDNA in smaller fragments of 500 bp directly from the initial extraction. These PCR amplifications were performed in 10 ll reactions using 5 ll of HotStart-IT Taq Master Mix
(2 ), 0.2 ll each of the heavy and light strand primers (see Supplementary Table 1) at a concentra- tion of 10 lM, 2 ll of unquantified DNA extraction, and 2.6 ll of HPLC water.
