Subspecies
This recently discovered species is distinguished from all other members of the genus by its almost entirely dark blue plumage and its deeply forked tail. The female resembles those of several congeners, notably Orange-throated Sunangel (Heliangelus mavors). However, present species is apparently not closely related to any congener.
The following 2 subspecies are recognised:
johnsoni Graves, GR, Lane, O'Neill & Valqui, 2011 - Local in central Peru (Cordillera Azul, south-western Loreto).
regalis Fitzpatrick, Willard & Terborgh, 1979 - Northern Peru.
