dc.description.abstract We used mtDNA sequence data to confirm that the controversial 100-year-old holotype of the Bogotá sunangel () represents a valid species. We demonstrate that is genetically well differentiated from taxa previously hypothesized to have given rise to the specimen via hybridization. Phylogenetic analyses place as sister to a clade of mid- to high-elevation Andean species currently placed in the genera and , presumed extinct, has never been observed in nature by biologists. We infer that the species occupied a restricted distribution between the upper tropical and temperate zones of the northern Andes and that it was most probably driven to extinction by deforestation that accompanied human population growth during the nineteenth and early twentieth centuries. We demonstrate the feasibility of obtaining DNA from nearly microscopic tissue samples from old hummingbird specimens and suggest that these methods could be used to resolve the taxonomy of dozens of avian taxa known only from type specimens. en
