Subspecies
No subspecies.
Crimson-breasted Gonolek (Laniarius atrococcineus) and Black-headed Gonolek (Laniarius erythrogaster) (Sibley and Monroe 1990, 1993) are retained as separate species contra Dowsett and Forbes-Watson (1993) who include erythrogaster as a subspecies of Crimson-breasted Gonolek (Laniarius atrococcineus).
Was formerly held to compose a superspecies with Crimson-breasted Gonolek (Laniarius atrococcineus), Yellow-crowned Gonolek (Laniarius barbarus) and Papyrus Gonolek (Laniarius mufumbiri), some authors including Yellow-breasted Boubou (Laniarius atroflavus) in this group. Recent molecular-genetic studies indicate that this species is sufficiently closely related to Yellow-crowned Gonolek (Laniarius barbarus) for the two to be regarded as a superspecies, that Papyrus Gonolek (Laniarius mufumbiri) and Yellow-breasted Boubou (Laniarius atroflavus) are a sister-group in same lineage, and that the four are only distantly related to Crimson-breasted Gonolek (Laniarius atrococcineus).
