The small red brocket (Mazama bororo) is a small species of deer in the family Cervidae. It is endemic to Atlantic Forest in Paraná and São Paulo in southeastern Brazil. This species, which only was scientifically described in 1996, is threatened by habitat loss. Though its size and structure most resemble that of the pygmy brocket (M. nana), its coloration is very similar to that of the red brocket (M. americana). It resembles hybrids between these two species even more closely, but differs from both, and their hybrids, in karyotype.
