Dibiyaso a.k.a. Bainapi is a Papuan language of Western Province, Papua New Guinea (Bamustu, Makapa, and Pikiwa villages). It is sometimes classified with the Bosavi languages. Søren Wichmann (2013)[3] tentatively considers it to be a separate, independent group. Pawley and Hammarström (2018) note that similarities between Bosavi and Dibiyaso are likely due to loanwords, therefore leaving Dibiyaso as unclassified.[4]

Dibiyaso is spoken in Bamustu (7°54′02″S 142°58′57″E / 7.900569°S 142.982551°E / -7.900569; 142.982551), Makapa (7°56′16″S 142°34′34″E / 7.937872°S 142.576135°E / -7.937872; 142.576135) , and Pikiwa (7°54′20″S 142°43′02″E / 7.905445°S 142.717106°E / -7.905445; 142.717106) villages of Gogodala Rural LLG, Western Province, Papua New Guinea.[5][6]

There is 19% lexical cognacy with Turumsa, suggesting contact or perhaps even a genetic relationship Doso–Turumsa language.[7]
