Has often been considered conspecific with T. australis (which see) of Madagascar; on basis of differences in cere colour, it seems most appropriate to consider it as being closest to T. australis, T. pembaensis and T. sanctithomae. Usually considered conspecific with T. delalandii but differs in having yellow-green vs (green-tinged) grey crown, neck and mantle (3);  yellow-green vs (yellow-tinged) grey throat to mid-belly (2);  grey-washed green vs  yellow-green rump and tail (2).Original description of wakefieldii included two different spellings (wakefieldi on plate); former selected by First Revisers#R. Present species rather variable; further study will probably reduce the number of valid races. Proposed races here synonymized include granviki (subsumed within gibberifrons), clayi (into orientalis), and chobiensis and damarensis (both into schalowi). Fifteen subspecies currently recognized.
