E16/E17/E18/E19/E20/E21/E22/E23/E24 has two entries Teke-Eboo [ebo] and Teke-Nzikou [nzu]. Two such entities are frequently enumerated separately but the recent comparison by Ruth Raharimanantsoa 2012 shows that such a distinction is untenable linguistically. Thus the two entries should be merged. See also: Teke-Nzikou [nzu].
