Kontanáwa (Panoan, thought to be extinct until 2002) is missing from E16/E17/E18/E19/E20/E21/E22/E23/E24/E25/E26/E27 Maria S. de Aguiar 2007: 40 . However, no linguistic data has been published to contradict or verify that Kontanáwa is a different language (as opposed to merely a dialect of a different ethnic group, or a different ethnic group who no longer speak their ancestral language) from other Nawa-languages ( Maria S. de Aguiar 2007 , Tastevin, Constant 1919 ). If not a distinct language, Kontanáwa should at least be included as a dialect of another language.
