Taxonomy complex and not fully understood. Commonly considered conspecific with T. helleri and T. ludoviciae (which see); also, most races of T. pelios have in the past been included in present species. Until recently considered conspecific also with T. abyssinicus, T. roehli and T. smithi; see those species. Races milanjensis and swynnertoni may in due course be considered for species rank; study needed. Hybridization with T. libonyana claimed in Zimbabwe and South Africa. Six subspecies recognized.
