Taxonomy

The genus Urochroa was introduced in 1856 by the English ornithologist John Gould to accommodate the rufous-gaped hillstar which is thus the type species.^[1][2] The genus name combines the Ancient Greek oura meaning "tail" with khroa meaning "colour" or "complexion".^[3]

The green-backed hillstar was formerly considered to be a subspecies of the rufous-gaped hillstar.^[4][5]

Species

The genus contains two species.^[5]
