Rusty-flanked Robin-chat (Dessonornis macclounii)

Hitherto treated as conspecific with D. anomalus and D. mbuluensis, but (along with D. mbuluensis) differs from D. anomalus by its (olive-tinged) dull dark grey vs dull olive-rufous upperparts (2); clear white vs white-tinged narrow grey supercilium (3); blackish vs grey face and moustachial area (2); more intense white of throat (and extending more onto upper breast in D. macclounii) (ns[1–2]); less extensive grey of breast (much darker in D. mbuluensis) with more white on mid-belly (ns[1–2]); more rufous, less olive-ochreish lower flanks and undertail-coverts (ns[1–2]). Race grotei greyer on crown and back, more chestnut on rump, vent and in tail, and possibly distinct vocally; further study may accord it species rank. Two subspecies recognized.
