Lule–Vilela languages
The two Lule–Vilela languages constitute a small, distantly related language family of northern Argentina. Kaufman found the relationship likely and with general agreement among the major classifiers of South American languages. Viegas Barros published additional evidence from 1996–2006. However, Zamponi considers Lule and Vilela each as language isolates, with similarities being due to contact.
