tlailotlacan.

An area with this name occurs on the western edge of Teotihuacan; it was a Zapotec enclave in the Classic period.
Michael W. Spence, "Tlailotlacan, A Zapotec Enclave in Teotihuacan,"in Janet Catherine Berlo, Art, Ideology, and the City of Teotihuacan: A Symposium at Dumbarton Oaks (Washington, D.C.: Dumbarton Oaks, 1992)), 59.

A place with this name existed in Chalco. It was an "outgrowth of Itztlacoçauhcan's secondary rulership." (seventeenth century, central Mexico)
Susan Schroeder, Chimalpahin and the Kingdoms of Chalco (Tucson: University of Arizona Press, 1991), 73–74.

Chimalpahin's eighth relación says, "We who are the descendants of the Tlailotlacan Tecpan, where the rulers, the loved ancients and loved tlahtoque Chichimeca, the tlahtoque and teuctin Tlailotlaca lived and governed. Hence it is called [the] 'Tlailotlacan Tecpan archive.'"

There was a "town and barrio" of Tlailotlacan in Texcoco, (Tetzcoco) "in the same way that other towns are called Tlailotlacan." Jiménez Moreno believed that the Tlailotlaque were "probably Mixtec peoples, perhaps related to Olmecoid groups who were in Amecameca."

There was a Tlailotlacan "barrio of Chiauhtlan" and a Tlailotlacan "division of Texcoco," according to Frances Berdan.

The division in Texcoco (Tetzcoco) has also been called an ethnically-based parcialidad.

Ben Johnson is studying the usage of calpolli, tlaxilacalli, altepemaitl, and tlailotlacan in the Tetzcocan context, as observed at the meeting of the Northeastern Nahuatl Group at Yale University, May 2017.
