The Collared Anteater, Tamandua tetradactyla (Linnaeus, 1758), is a small mammal predator of ants. There are few studies describing which species are in fact consumed by them. This study was aimed to investigate the diversity and abundance of local species of ants preyed by the T. tetradactyla. Eight samples of stomach contents collected in the period from 2009 to 2014 were analyzed and identified at the lowest possible taxonomic level. We found 5,906 ants distributed in 16 species. The most abundant samples were number 2 and 4 with almost 2,000 individuals and the highest richness and abundance was Myrmicinae subfamily with eight species and 3,721 individuals. The ant richness found in this research demonstrates that the anteaters are generalists and opportunistic about their diet, not having a preference for a particular species, but rather for those insects that are available in their habitat.
