Metyctires
The Metyktire are an indigenous people in Brazil .
The people probably have around 100 members and live in voluntary isolation in an inaccessible area around 2000 kilometers northwest of Rio de Janeiro . The Metyktire is part of the Kayapo in the Menkregnoti Reserve in the Amazon basin . They speak an older form of the Kayapo language and are mostly bare except for a penis covering. The men wear black-and-red face paints and disks ( lip pegs ) in their lower lip , while the women traditionally shave their heads bald.
The existence of the people became known in May 2007 when three families of the Metyktire briefly visited the Kayapo village of Kapot in the state of Mato Grosso . The Kayapo suspect that the Metyktires are descendants of several Kayapo families who retreated deeper into the jungle after an argument with their relatives in the 1950s when Orlando Villas Bôas , an anthropologist and Native American defender, arrived .
