Boma–Dzing languages

The Boma–Dzing languages are a clade of Bantu languages coded Zone B.80 in Guthrie's classification. According to Nurse & Philippson (2003), some of Guthrie's B.80 (Tiene, Mfinu, Mpuono) are related to the Teke languages (B.70), and some Yansi varieties belong with the Yaka languages (H.30), but the rest form a valid node. They are:
 * Boma: Boma, Mpe (Kempee), Nunu
 * Ding: Ding (Dzing, Di), Ngul (including Ngwi), Lwel (Kelwer), Mpiin, West Ngongo, Nzadi
 * Tsong
