Papi–Asaba languages
The Papi and Asaba languages form a small family of two somewhat distantly related languages of northern Papua New Guinea, namely Papi and Suarmin.
Donald Laycock classified them as part of a Walio–Papi, a.k.a. Leonhard Schultze, branch of his Sepik–Ramu proposal. Malcolm Ross breaks up Walio–Papi, and suggests that the Papi languages may instead be part of the Sepik Hill branch of the family. Glottolog does not find the evidence of a Papi family to be convincing. Foley and Usher retain them in Leonhard Schultze.
