ETHNONYMS: Ethnonyms in the earliest sources that possibly refer to the prehistoric Nivaclé are Guentusé, Mathlelá, and Lateshelechí-Maiceros. Other ethnic groups refer to them as Ashlushlai, Suhín, Sotirgaik, and Wentusij. Creoles call them by many other names that are based on the latter. In Argentina they are generally called Chulupí and in Paraguay Churupí.
