Generally considered separate species from C. cailliautii, and here treated as such owing to its densely barred (not spotted) underparts (3); unmarked (not white-spotted) upperparts (3); yellower underparts (yellow-tinged white in other forms) (1); darker tail (ns); and “narrow band” of intergradation “a little beyond the south-eastern margin of the Congo Forest”#R (score 2), as well as in Angola. Race permista sometimes included in C. cailliautii (as in HBW), or treated as separate species, but only distinctions are blackish vs greenish-tinged blackish tail (1) and female without vs with broad red on nape (3); suggestion of only rare hybridization in Ghana called in question and width of hybrid zone not clear; voices “identical”#R. Form togoensis (Ghana to S Nigeria) synonymized with permista. Two subspecies recognized.
