Taxonomy rather complicated, and much debated. In the past, commonly placed in monospecific Scoptelus on basis of rather straight bill; later, under arrangement whereby family divided into two genera, it was often placed in Phoeniculus, but DNA studies in particular indicate closer affinities with Rhinopomastus. Closely related to R. cyanomelas; the two sometimes considered conspecific, intergrading in S Angola and SE DRCongo, with hybridization also documented, but elsewhere (e.g. W Zambia) they appear ecologically separated; further, differences in morphology and vocalizations suggest that they are probably better treated as separate species, though some authorities suggest that they are vocally identical#R. Race anchietae may be better placed with R. cyanomelas#R. Birds from Angola and W Zambia, described as race anomalus, now considered inseparable from anchietae; those from Sudan described as cavei apparently inseparable from emini. Four subspecies recognized.
