Wilbrink (2004) lists 4 distinct language varieties.Wilbrink, Ans (2004). ''The Kopkaka of Papua: Provisional notes on their language, its language affiliation and on the Kopkaka culture.''

Noting insufficient evidence, Pawley and Hammarström (2018) leave Bayono–Awbono as unclassified rather than as part of Trans-New Guinea. However, according to Dryer (2022), based on a preliminary quantitative analysis of data from the ASJP database, Bayono–Awbono is likely to be a subgroup of Trans–New Guinea. Timothy Usher finds enough evidence to classify Awbono–Bayono within the Greater Awyu (Digul River) family.Usher, TimothyPronouns
