River Ja, Cameroon.
Hitherto treated as conspecific with S. erythrothorax, but differs in its yellowish-tan or bright orange-yellow vs dull orange breast (2); creamy-white or yellow-washed vs white belly (1); song with higher number of shorter notes (2) delivered in longer phrases (2)#R. It differs from S. pyrrholaemus in characters given under that species. Race sanghensis differs from nominate by its bright orange-yellow vs yellowish throat (2); bright orange-yellow vs yellowish-tan breast (2); pale yellow vs creamy-white belly (1); study of vocalizations needed to determine any consistent differences. Race rudderi, described very recently as a phylogenetic species, has not been scored but morphological differences are obviously rather minor, while genetic data clearly place it within same clade as nominate race and sanghensis. Proposed race mabirae (DRCongo and Uganda) merged with xanthogaster. Three subspecies recognized.
