Has been considered conspecific with C. lemprieri; songs rather similar, and separation based mainly on plumage. Until recently considered conspecific with C. magnirostris, which proves to be vocally rather close to Javan and Bornean taxa of present species but not to mainland subspecies, and molecular analysis places Javan and Bornean taxa some distance from mainland forms#R; thus evidence emerging that mainland taxa may require separation as one species, with perhaps two species (which differ vocally) in Indonesia#R. Race mardii, described from Panaitan I, off Java, sometimes recognized. Some evidence of hybridization with C. sumatrensis in Malay Peninsula. Race montanus previously and erroneously listed as coeruleatus in HBW and elsewhere#R, but this name is unavailable#R. Seven subspecies recognized.
