See A. woodwardi and A. merrotsyi. In HBW race oweni considered to fall within range of variation of nominate, but here recognized (“small and rufous but with a white belly”#R). In recent study, races oweni, whitei and rowleyi all separated as species chiefly on molecular distances#R, but this arrangement is weakly supported by morphological and ecological evidence: thus, species rank for oweni is based on genetic distance, minor plumage differences, biogeography and habitat (sandhill vegetation)#R; for whitei (unsampled genetically) on habitat (rocky-outcrop vegetation) and relatively strong morphological characters (“large and rufous” vs “large and grey-brown” of nominate)#R; for rowleyi on genetic distance, geographical isolation and morphology#R, namely shorter tail (but sample size very small, with overlap apparent), slightly paler upperparts and underparts and (possibly) other very minor characters#R. Fuller gathering and presentation of all lines of evidence recommended in order to allow rigorous assessment of these taxa. Four subspecies recognized.
