The endangered southern muriqui or mono [Brachyteles arachnoides (É. Geoffroy, 1806)], is a primate endemic to the Atlantic Forest of Brazil. One known extant population is found at the southern limit of its distribution, in the state of Paraná, where it is regionally classified as Critically Endangered. Here, we report on a new population in southern Brazil. Additionally, we express our concern about the conservation status of this species in Paraná, because both populations are in small, isolated and unprotected forest fragments.
