Chiriba (Chiriva) is a poorly attested language of Moxos Province, Bolivia which may have belonged to the Panoan family. All that was recorded of it was a list of seven words; several of these resemble Panoan languages, especially Pakawara, and none resemble other language families. Unattested Chumana is reported to have been related.David Fleck, 2013, Panoan Languages and Linguistics, Anthropological Papers of the American Museum of Natural History #99
