The Rufiji–Ruvuma languages are a group of Bantu languages established by Gloria Waite (1979) and subsequent researchers: N10 (less Manda), P10 (Ngindo moved to N10), P20.
The languages, or clusters, along with their Guthrie identifications are:
Ruvuma (P20): Yao–Mwera Makonde: Makonde–Machinga, Mabiha Mbinga Ruhuhu (N10): Matengo, Mpoto Matandu (P10): Matumbi, Ndengereko (Rufiji) Lwegu: Ngindo (P10), Ndendeule, Ndwewe (N10) Songea (N10): Ngoni
Among the Guthrie languages not specifically classified are Nindi (N10, said to be close to Ndendeule); and Tonga of Malawi (N10).
Nurse moves Manda to Bena–Kinga, but Ehret keeps it here.
