|Region||Papua Province, Indonesia|
Bayono, Awbono, and Densar constitute a recently discovered dialect cluster spoken in Indonesian Papua Province south of the Somahai languages. All that is known of them are a few hundred words recorded in first-contact situations recorded in Wilbrink (2004) and Hischier (2006). Noting insufficient evidence, Pawley and Hammarström (2018) leave it as unclassified rather than as part of Trans-New Guinea. Timothy Usher finds enough evidence to classify them within the Greater Awyu (Digul River) family.
The pronouns demonstrate resemblances to the neighboring Ok and Greater Awyu languages, and the pronouns are consistent with Bayono-Awbono belonging to the Trans–New Guinea family:
