Arikapu

Aricapú ( Aricapú, Arikapú, Maxubí ) is an almost extinct Native American language belonging to the Yabutian group of the linguistic family, which is spoken by the Arikapu people living on the headwaters of the Branco River and on the tributaries of the right bank of the Guapor River in the state of Rondonia in Brazil. It looks like the language of Yabuchi. Many switched to the Tupari language. They are also among other ethnic groups, primarily among the Tupar people.
