Zoothera piaggiae and Z. tanganjicae (Sibley and Monroe 1990, 1993) have been lumped under Z. piaggiae following Dowsett and Forbes-Watson (1993) who include tanganjicae as a subspecies of Z. piaggiae on the basis that morphological differences are slight, vocal characters are of little help in determining species limits in Zoothera, and, pending evidence that the parapatry claimed by Prigogine exists between breeding populations of the two in eastern DRC (rather than being influenced by the altitudinal movements of one or the other), the two are best treated as conspecific. BTWG adopts this position.
