SIL has not done extensive investigations in Chocholteco of Oaxaca (also known as Ngigua).

Mazatec includes four or five important variants (in Oaxaca, Veracruz and Puebla). The Summer Institute of Linguistics has done investigations in four of these.

Popoloca has six important variants in the state of Puebla.

The name Ixcatec is used for another language of this family, believed by many to be extinct, and also for a variant of Mazatec.
