Subspecies
Differences in display and behaviour do not suggest particularly close relationship with Green-tailed Trainbearer (Lesbia nuna). May be more closely related to Red-tailed Comet (Sappho sparganurus). Subspecies eucharis of Green-tailed Trainbearer (Lesbia nuna), formerly thought to have come from Colombia, was provisionally placed in present species.
Proposed subspecies aequatorialis doubtfully distinct from nominate, since only difference documented is tail length which is quite a variable character within nominate. "Lesbia ortoni" (= "Zodalia glyceria") is probably a hybrid of present species and Purple-backed Thornbill (Ramphomicron microrhynchum).
The following 3 subspecies are recognised:
victoriae (Bourcier & Mulsant, 1846) - Andes of north-eastern Colombia (Norte de Santander to Bogotá); Andes of southern Colombia (Nariño) and Ecuador.
juliae (Hartert, 1899) - Andes of northern and central Peru.
berlepschi (Hellmayr, 1915) - Andes of south-eastern Peru.
