Taxonomy:

Drymoeca undosa

Has been considered conspecific with C. simplex and, more frequently, with C. stierlingi; but no intergradation with C. simplex where ranges meet (in N Tanzania and SW Kenya); narrow (15–20 km wide) zone of hybridization with C. stierlingi in C Zambia and N Malawi, but quite distinct in plumage and songs (hybrids intermediate in appearance, may have intermediate songs). Aberrant juveniles of race cinereus having buffy-olive underparts were erroneously described as a separate taxon, Camaroptera brachyura congica. Four subspecies recognized.
