This species and C. minullus sometimes placed in genus Chalcomitra. Race bineschensis poorly differentiated from, and sometimes synonymized with, orphogaster; moreover, it is isolated from other races of present species, and has been suggested also as being possibly misidentified C. reichenowi. Proposed races luehderi (described from Bipindi, in Cameroon) and insularis (Bioko) synonymized with nominate; uellensis (Koloka, Angu and Amadi, on R Uelle, in DRCongo) merged with orphogaster. Females in Cameroon and DRCongo having light yellow pectoral tufts and red breastband but no metallic plumage described as race ogilviegranti, but shown to be aberrantly plumaged females of nominate. Four subspecies recognized.
