The Pauserna are an indigenous people in Bolivia and Brazil who live along the upper Río Guaporé.

[2] The people derive their name from the fact that the pao cerne tree is abundant in their area.

[2][4] Most likely the Pauserna migrated to Bolivia from Paraguay centuries before when the Guaraní attacked the frontiers of the Incan empire.

He visited them on the Brazilian side of Rio Guaporé in a village called Orikoripe.

[8] Pauserna are also known as Araibayba, Carabere, Guarasug'we, Guarayuta, Itatin, Moterequoa, Pau Cerna and Pauserna-Guarasug'we.

[2] The Pauserna make and wear bark cloth and woven cotton garments.

Girls were secluded for a month at puberty, fed a restricted diet, and tattooed on their arms and breasts.
