Résumé :	This study analyses the biogeography and taxonomy of the hummingbird taxon Haplophaedia, based on the examination of biometric and plumage characters, and summarizes various life history traits. Currently, the genus Haplophaedia comprises two species, H. aureliae (ssp. aureliae, caucensis, floccus, galindoi, russata, assimilis, affinis) and H. lugens. Based on biogeographical and morphological aspects, we suggest that H. assimilis (ssp. assimilis, affinis) is distinct at species level. Due to significant geographical variation within the range of H. aureliae, we give subspecific recognition to the southernmost, allopatric subpopulation in Ecuador, named as H. aureliae cutucuensis subspec. nov. It is postulated that Haplophaedia evolved prior to the Pleistocene in the "cloud forests" of the northern Andes, subsequently invading similar habitats in the western and central Andes during glacial phases.
