Achires

A large number of languages known only from brief mentions are thought to have been Uto-Aztecan languages, but became extinct without being documented. The following list is based on .

* San Nicolás (Nicoleño): spoken in California, thought to be a Takic language.
*Giamina/Omomil: Kroeber (1907) and Lamb (1964) believe Giamina may constitute a separate branch of Northern Uto-Aztecan, although Miller (1983) is uncertain about this. It was spoken in Southern California.
*Vanyume: a Takic language of California
*Acaxee (Aiage): closely related to Tahue, a Cahitan language, linked with Tebaca and Sabaibo.
*Amotomanco (Otomoaco): uncertain classification, possibly Uto-Aztecan. (See Troike (1988) for more details.)
* Cazcan (Caxcan): sometimes considered to be the same as Zacateca, although would only consider these to be geographical classifications.
*Baciroa: closely connected to Tepahue
*Basopa
*Batuc: possibly an Opata dialect
*Cahuimeto
*Cahuameto: probably belongs with Oguera and Nio
*Chínipa: may be a Tarahumaran language close to Ocoroni, since colonial sources claim the two are mutually intelligible. It may also instead be a local name for a variety of Guarijío.
*Coca: spoken near Lake Chapala.
*Colotlan: a Pimic language closely related to Tepehuan, or Teul and Tepecano
*Comanito: a Taracahitic language closely related to Tahue
*Concho: probably a Taracahitic language (Troike 1988). Subdivisions include Chinarra and Chizo; Toboso is possibly related to Concho as well.
*Conicari: a Taracahitic language closely related to Tahue
* Guachichil: possibly a variant or close relative of Huichol
*Guasave: possibly a Taracahitic language, or may instead be non-Uto-Aztecan language possibly related to Seri due to the speakers' maritime economy (Miller 1983). Dialects include Compopori, Ahome, Vacoregue, and Achire.
*Guazapar (Guasapar): probably a Tarahumara dialect, or it may be more closely related to Guarijío and Chínipa. Guazapar, Jova, Pachera, and Juhine may possibly all be dialects of Tarahumara.
*Guisca (Coisa)
*Hio: possibly a Taracahitic language
*Huite: closely related to Ocoroni, and may be Taracahitic
*Irritila: a Lagunero band
*Jova (Jobal, Ova): most often linked with Opata, although some scholars classify it as a Tarahumara dialect. Miller (1983) considers it to be "probably Taracahitan."
* Jumano; also Humano, Jumana, Xumana, Chouman (from a French source), Zumana, Zuma, Suma, and Yuma. Suma is probably the same language, while Jumano is possibly Uto-Aztecan. (Not to be confused with the Jumana language of Colombia.)
*Lagunero: may be the same as Irritila, and may also be closely related to Zacateco or Huichol.
*Macoyahui: probably related to Cahita.
*Mocorito: a Tahue language, which is Taracahitic.
*Naarinuquia (Themurete?): Uto-Aztecan affiliation is likely, although it may instead be non-Uto-Aztecan language possibly related to Seri due to the speakers' maritime economy.
*Nacosura: an Opata dialect
*Nio: completely undocumented, although it is perhaps related to Ocoroni.
*Ocoroni: most likely a Taracahitic language, and is reported to be mutually intelligible with Chínipa, and similar to Opata. Related languages may include Huite and Nio.
*Oguera (Ohuera)
*Patarabuey: unknown affiliation (Purépecha region near Lake Chapala), and is possibly a Nahuatl dialect.
*Tahue: may also include Comanito, Mocorito, Tubar, and Zoe. It is possibly a Taracahitic language, and is definitely not Nahuan.
*Tanpachoa: unknown affiliation, and was once spoken along the Río Grande.
*Tecuexe: speakers were possibly part of a "Mexicano" (Nahua) colony.
* Teco-Tecoxquin: an Aztecan language
* Tecual: closely related to Huichol. According to Sauer (1934:14), the "Xamaca, by another name called Hueitzolme uichol all ... speak the Thequalme language, though they differ in vowels."
*Témori: may be a Tarahumara dialect.
*Tepahue: possibly a Taracahitic language. Closely related languages or dialects include Macoyahui, Conicari, and Baciroa.
* Tepanec: an Aztecan language.
* Teul (Teul-Chichimeca): a Pimic language, possibly of the Tepecano subgroup.
* Toboso: grouped with Concho.
*Topia: perhaps the same as Xixime (Jijime).
*Topiame: possibly a Taracahitic language.
* Totorame: grouped with Cora.
*Xixime (Jijime): spoken by the Xiximes, possibly a Taracahitic language. Subdivisions are Hine and Hume. Its links with Acaxee are uncertain.
* Zacateco: often considered the same as Acaxee, although this is uncertain. It is possibly related to Huichol, although Miller (1983) leaves it as unclassified.
*Zoe: possibly a Taracahitic language, with Baimena as a subdivision. It is possibly affiliated with Comanito.
