French: Gonolek à ventre rouge German: Scharlachwürger Spanish: Bubú Cabecinegro
Other common names: Abyssinian/Red-bellied Gonolek, Black-headed Bush-shrike, Barbary Shrike

Taxonomy: Lanius erythrogaster Cretzschmar, 1829, Kordofan, Sudan.
Was formerly held to compose a superspecies with L. atrococcineus, L. barbarus and L. mufumbiri, some authors including L. atroflavus in this group. Recent molecular-genetic studies indicate that this species is sufficiently closely related to L. barbarus for the two to be regarded as a superspecies, that L. mufumbiri and L. atroflavus are a sister-group in same lineage, and that the four are only distantly related to L. atrococcineus. Monotypic.

Distribution: NE Nigeria, S Chad, N & C Cameroon (S to Adamawa Plateau) and N Central African Republic E to E Sudan, W Eritrea and W Ethiopia, S to E DRCongo, N Tanzania and W Kenya; also in SE DRCongo (Lualaba valley from about Kabalo S to L Kisale and Bukama).
