The genus Upupa was created by Linnaeus in his Systema naturae in 1758. It then included three other species with long curved bills:    U. eremita (now Geronticus eremita), the northern bald ibis U. pyrrhocorax (now Pyrrhocorax pyrrhocorax), the red-billed chough U. paradisea (Wikipedia).

They vary mostly in size and the depth of colour in the plumage. Two further subspecies have been proposed, U. e. minor in South Africa and U. e. orientalis in north western India (Wikipedia).
