Thought to be part of a clade that contains also C. flavigularis, C. klaas and C. caprius#R. Sometimes treated as polytypic on basis of length of tail and wing, with tail shorter on São Tomé, Príncipe and Pagalu (insularum), intermediate on Bioko (intermedius), longer in most of continental Africa (cupreus) and short in S Africa (sharpei), and on markings on undertail-coverts, but considerable overlap in these traits is evident from one region to another. Treated as monotypic.
