New South Wales, Australia.
Closely related to H. cochinchinensis, with which was in the past sometimes considered conspecific. Taxon formosanus formerly placed in present species, but has been shown to be virtually identical to nominate race of H. cochinchinensis, to which it clearly belongs (see below). Himalayan form nudipes differs from nominate caudacutus apparently in migratory habits, and in having all-dark lores and blue-glossed (not green-glossed) upperparts, suggesting considerable distinctiveness; specimens in NHMUK from China, however, appear intermediate, having white lores and blue-glossed upperparts. Proposed race bourreti (from Laos, where a presumed passage migrant) is indistinguishable from nominate. Two subspecies recognized.
