Guarasugwe

The Guarasugwe, also called Pauserna, are a Tupi-Guarani people of the upper Guaporé River on the Bolivia-Brazil border. Descended from Guaraní migrants from Paraguay, they once formed one people with the Guarayo but stayed independent when the Guarayo branch entered missions, keeping their Tupí tongue and customs of cross-cousin marriage and couvade in the riverside forests.
