Biyanda-Buli language

Biyanda ("Ɓìyàndà") and Buli ("Ɓùlì") constitute a Gbaya language of the Central African Republic. "Ethnologue" groups them as Southwest Gbaya, but it is not clear how many of the Southwest varieties are part of the same language; Toongo and Mbodomo, for example, are not closely related, though Toongo speakers identify ethnically as Buli, and "Ethnologue" also lists Mbodomo as a separate language.
