Lafofa languages in the context of "Kordofanian languages"

The Kordofanian languages are a geographic grouping of five language groups spoken in the Nuba Mountains of the South Kordofan region of Sudan: Talodi–Heiban languages, Lafofa languages, Rashad languages, Katla languages and Kadu languages. The first four groups are sometimes regarded as branches of the hypothetical Niger–Congo family, whereas Kadu is now widely seen as a branch of the proposed Nilo-Saharan family. The Kordofanian languages may be the oldest group of languages in the region.
