Yetfa and Biksi (Biaksi) are dialects of a language spoken in West Papua Indonesia and across the border in Papua New Guinea. It’s a trade language in West Papua up to the PNG border. The language is not close to others. Ross (2005) following Laycock & Z’Graggen (1975) places Biksi in its own branch of the Sepik family but there is little data to base a classification on.
