Atatláhuca–San Miguel Mixtec

Atatláhuca–San Miguel Mixtec is a diverse Mixtec language of Oaxaca.

Egland & Bartholomew found six dialects which had about 70% mutual intelligibility with each other:

San Esteban Atatláhuca + Santa Lucía Monteverde
Molinos
Itundujía
Yosondúa + San Miguel el Grande + Chalcatongo
Yolotepec
Teita

Ethnologue notes that two additional varieties Egland & Bartholomew had not looked at, Sinicahua and Tijaltepec, are about as similar.
