Ethnologue lists Mixistlán as well, but Wichmann counts that as Tlahuitoltepec Mixe.
A new variety of Midland Mixe has been recently documented in the village of San Juan Bosco Chuxnabá in San Miguel Quetzaltepec municipality, Oaxaca by Carmen Jany and other linguists.[3][4][5]
Phonology
Orthography from Jany (2011) is in angle brackets where it differs from IPA.[6]
/æ/⟨ä⟩, /ø/⟨ö⟩, and /ʊ/⟨ü⟩ are marginal vowels. [ø] and [ʊ] only occur as allophones of /o/ and /u/, respectively, in palatalized environments, and [æ] sometimes alternates with /a/.[6]
