The purple-bibbed whitetip (Urosticte benjamini) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae. It is found in Colombia and Ecuador.
Taxonomy and systematics
The purple-bibbed whitetip and rufous-vented whitetip (Urosticte ruficrissa) have been treated as conspecific and as distinct species, each by multiple authors. Since the early 2000s there is consensus that they are species in their own right. They are the only members of their genus and both are monotypic.
