The Mairasi languages, also known as Etna Bay are a small independent family of Papuan languages in the classifications of Malcolm Ross and Timothy Usher, that had been part of Stephen Wurm's Trans–New Guinea proposal. They are named after Etna Bay, located in the southeastern corner of West Papua province, in Indonesia.
The Greater Awyu or Digul River languages, known in earlier classifications with more limited scope as Awyu–Dumut (Awyu–Ndumut), are a family of perhaps a dozen Trans–New Guinea languages spoken in eastern West Papua in the region of the Digul River. Six of the languages are sufficiently attested for a basic description; it is not clear how many of the additional names may be separate languages.
The Asmat – Kamrau Bay languages are a family of a dozen Trans–New Guinea languages spoken by the Asmat and related peoples in southern Western New Guinea. They are believed to be a recent expansion along the south coast, as they are all closely related, and there is little differentiation in their pronouns.
The Marind–Yaqai (Marind–Yakhai) languages are a well established language family of Papuan languages, spoken by the Marind-anim. They form part of the Trans–New Guinea languages in the classifications of Stephen Wurm and Malcolm Ross, and were established as part of the Anim branch of TNG by Timothy Usher.
The Dani or Baliem Valley languages are a family of clearly related Trans–New Guinea languages spoken by the Dani and related peoples in the Baliem Valley in the Highland Papua, Indonesia. Foley (2003) considers their Trans–New Guinea language group status to be established. They may be most closely related to the languages of Paniai Lakes, but this is not yet clear. Capell (1962) posited that their closest relatives were the Kwerba languages, which Ross (2005) rejects.
Fasu, also known as Namo Me, is one of the Kutubuan languages of New Guinea.
The Timor–Alor–Pantar (TAP) languages are a family of languages spoken in Timor, Kisar, and the Alor archipelago in Southern Indonesia. It is the westernmost Papuan language family that survives, and one of two such outlier families in east Nusantara.
The Kamula–Elevala languages are a small family of the Trans–New Guinea languages spoken in the region of the Elevala River.
The Gogodala–Suki or Suki – Aramia River languages are a small language family of Papua New Guinea, spoken in the region of the Aramia River.
The Ok languages are a family of about a dozen related Trans–New Guinea languages spoken in a contiguous area of eastern Irian Jaya and western Papua New Guinea. The most numerous language is Ngalum, with some 20,000 speakers; the best known is probably Telefol.
The Madang or Madang–Adelbert Range languages are a language family of Papua New Guinea. They were classified as a branch of Trans–New Guinea by Stephen Wurm, followed by Malcolm Ross. William A. Foley concurs that it is "highly likely" that the Madang languages are part of TNG, although the pronouns, the usual basis for classification in TNG, have been "replaced" in Madang. Timothy Usher finds that Madang is closest to the Upper Yuat River languages and other families to its west, but does not for now address whether this larger group forms part of the TNG family.
The Kainantu–Goroka languages are a family of Papuan languages established by Arthur Capell in 1948 under the name East Highlands. They formed the core of Stephen Wurm's 1960 East New Guinea Highlands family, and are one of the larger branches of Trans–New Guinea in the 2005 classification of Malcolm Ross.
The Chimbu–Wahgi languages are a language family of New Guinea. They are sometimes included in the Trans–New Guinea proposal; Usher links them with the Engan languages in a Central New Guinea Highlands family.
The Engan languages, or more precisely Enga–Kewa–Huli or Enga – Southern Highland, are a small family of Papuan languages of the highlands of Papua New Guinea. The two branches of the family are rather distantly related, but were connected by Franklin and Voorhoeve (1973).
The Dagan or Meneao Range languages are a small family of Trans–New Guinea languages spoken in the Meneao Range of the "Bird's Tail" of New Guinea, the easternmost Papuan languages on the mainland. They are the most divergent of the several small families within the Southeast Papuan branch of Trans–New Guinea.
The Yareban or Musa River languages are a small family of Trans–New Guinea languages spoken near the Musa River in the "Bird's Tail" of New Guinea. They are classified within the Southeast Papuan branch of Trans–New Guinea.
The Manubaran languages are a small family of Trans–New Guinea languages spoken around Mount Brown in the "Bird's Tail" of New Guinea. They are classified within the Southeast Papuan branch of Trans–New Guinea.
The Koiarian languages Koiari are a small family of Trans–New Guinea languages spoken in the "Bird's Tail" of New Guinea. They are classified within the Southeast Papuan branch of Trans–New Guinea.
The Greater Binanderean or Guhu-Oro languages are a language family spoken along the northeast coast of the Papuan Peninsula – the "Bird's Tail" of New Guinea – and appear to be a recent expansion from the north. They were classified as a branch of the Trans–New Guinea languages by Stephen Wurm (1975) and Malcolm Ross (2005), but removed by Timothy Usher (2020). The Binandere family proper is transparently valid; Ross connected it to the Guhu-Semane isolate based on pronominal evidence, and this has been confirmed by Smallhorn (2011). Proto-Binanderean has been reconstructed in Smallhorn (2011).
Foi, also known as Foe or Mubi River, is one of the two East Kutubuan languages of the Trans-New Guinea family spoken along Lake Kutubu and Mubi River, located in the Southern Highlands Province of Papua New Guinea. Dialects of Foi are Ifigi, Kafa, Kutubu, Mubi. A Swadesh list for the Foi language was documented by The Rosetta Project in 2010. The estimated number of Foi speakers as of 2015 is between 6,000 and 8,000.
