Yambe, a Congolese language of the Ndzem-Bomwali subgroup, is missing from E16/E17/E18/E19/E20/E21/E22/E23/E24/E25/E26/E27 ( Klieman, Kairn A. 1997 ). No other sources speak of a Yambe language of the Ndzem-Bomwali subgroup in the location given by Klieman, Kairn A. 1997 and further ethnolinguistic information is lacking. A clarification, with research on the ground and/or a closer comparison with Pomo and Kweso, is needed
