Guhu-Samane, also known as Bia, Mid-Waria, Muri, Paiawa, Tahari, is a divergent Trans–New Guinea language that is related to the Binanderean family in the classification of Malcolm Ross (2005).
The divergence of Guhu-Samane from other Binanderean languages may be due to extensive historical contact with Oceanic languages such as Numbami.
[2] Smallhorn (2011:131) gives the following dialects: The dialect differences are principally lexical, but two voiced obstruents also show regular variants.
The coronal obstruent is realized as /dz/ upriver in Bapi and Garaina, /d/ downriver to Asama, and /j/ farther downriver in Papua.
The voiced bilabial is realized as /b/ inland but as /w/ at the coast (Sinaba and Paiawa) (Handman 2015:102).
