Placed in its own subfamily on basis of primitive skeletal characters, which suggest link with trumpeters of family Psophiidae. Sometimes divided into three races, with recognition of petiti (Gabon to C DRCongo) and whitesidei (SC & E DRCongo), but in view of great individual variation in plumage within ranges of all three proposed races, and overlap of characters between them, species probably best treated as monotypic until more extensive studies made. Monotypic.
