The southern muriqui (Brachyteles arachnoides) is a muriqui (woolly spider monkey) species endemic to Brazil. It is found in the Brazilian states of Paraná, São Paulo, Rio de Janeiro, Espírito Santo and Minas Gerais. This New World monkey is known locally as mono carvoeiro, which translates to "charcoal monkey". The southern muriqui, B. arachnoides, has a solid black face, distinguishing it from the northern species, B. hypoxanthus, which has a black face mottled with pink.
