Lumnanas
Lumnanas is a self-designation of the people also known as Manjui, whose homeland lies in the western Chaco. They belong to the Mataco-Mataguayo linguistic family, alongside the Nivaclé and Maká. Their communities have lived in the borderlands of Paraguay, Bolivia and Argentina, including country near the Pilcomayo River and the interior of the northern Chaco. Dry forests and seasonal watercourses shape this vast plain.
