Southern extension of the geographic range of black-and-gold howler monkeys (Alouatta caraya)

The black-and-gold howler monkey ( Alouatta caraya ) is widely distributed in Brazil, Bolivia, Paraguay, and northeastern Argentina. Despite this wide distribution, it is locally threatened in some parts of its southern range by forest loss and fragmentation, and yellow fever outbreaks. We present 14 new localities of A. caraya occurrence in the Pampa biome of southern Brazil, extending its range southwards by approximately 100 km.
