Chiapanec language

Chiapanec is a presumably extinct indigenous Mexican language of the Oto-Manguean language family believed to have been spoken by the Chiapanec people. The 1990 census^[2] reported 17 speakers of the language in southern Chiapas out of an ethnic population of 32, but later investigations failed to find any speakers.^[3]

It is closely related to Mangue.
