Songa [sgo], alternative name Kisonga, is listed in E16/E17 as an Unclassified Bantu language of South Kivu province without a precise location or a population estimate. There is no sign of a language with that name in South Kivu province ( Kadima, Kamuleta 1983: 34-37 , Moeller, A. 1936 ) unless it is Kisanga ( Botne, Robert 2003: 423 ). If it is Kisanga, the Songa [sgo] entry is spurious because Kisanga falls under the Lega-Shabunda [lea] entry. See also: Lega-Shabunda [lea].
