Identity follows the river. Chíponki — downriver, historically the Shetebo. Réboki — upriver, the Konibo. Napónbekon — midriver, a newer term. On the Pisqui river: the Piskibo. Together, the teachers said, all are paro jonibo — people of the river. Accents and dialect shift slightly along the water.
Culture note. This is why the people are called Shipibo-Konibo with a hyphen: historically distinct river identities that merged over the last century. The names carry their geography in the body: Réboki, upriver, from the word for the nose's tip; Chíponki, downriver, from the word for the bottom. And 'Shipibo' itself: shipi, a small monkey, plus the plural -bo. The dialects differ mostly in accent — Konibo speech carries more nasalization (ikentian where Shipibo says iketian).
