The evidence presented by Doornbos and Bender 1983, Edgar 1991 that Mimi-Nachtigal is Maban is clearly insufficient. No other serious evidence for a Nilo-Saharan (or other) affiliation has appeared.

The Mimi language of Wadai, as documented by Nachtigal ( Lukas, Johannes and Völckers, O. 1938 ) is missing from E16/E17/E18/E19. The language has not been sighted for over a century and is therefore likely extinct. There is some evidence (body part terms) that Mimi-Nachtigal is related to the Maban group of languages ( George Starostin 2011 ).
