Violet-tailed Sylph (Aglaiocercus coelestis) - HBW 5, p. 659
French: Sylphe à queue violette
Spanish: Silfo Celeste
Taxonomy: Cynanthus cœlestis Gould, 1861, Ecuador.
Genus name formerly given as Cyanolesbia, but this is not applicable. Forms a superspecies with A.kingi and A. berlepschi. Formerly treated as a race of A. kingi, but morphology and range, especially altitudinal distribution, indicate species status more apt; female notably different from that of A. kingi. Proposed race pseudocoelestis best considered synonymous with nominate, since morphological differences are superficial. Two subspecies currently recognized.
Subspecies and Distribution:
- coelestis (Gould, 1861) - Pacific slope of W Andes of both Colombia and N & C Ecuador.
- aethereus (Chapman, 1925) - SW Ecuador, S from Zaruma.
- Least Concern Enlarge map
