Abstract: | A phylogeny of the hummingbirds of the genera Ramphodon, Eutoxeres, Glaucis, Threnetes, and Phaethornis is presented on the basis of external morphological characters. All 34 species of hermit hummingbirds are included in this study. Differences in 96 characters were examined with regard to their apomorphic (derived) or plesiomor‐phic (primitive) states, resulting in evolutionary trees drawn on the basis of cladistic principles. The most important results are: (1) “Ramphodon “ dohrnii is closer to Glaucis than to Ramphodon; (2) “Phaethornis” gounellei is the sister species to all Phaethornis and merits reevaluation as a separate genus, Anopetia; (3) Phaethornis philippii and P. koepckeae are the sister group to P. syrmatophorus, their straight bill having evolved independently of P. bourcieri; (4) the Phaethornis superciliosus/malaris species group includes P. longirostris as a third species; (5) Phaethornis subochraceus, P. pretrei, and P. augusti share a common ancestor, and (6) Phaethornis longuemareus (sensu Peters 1945) is polyphyletic, being comprised of four seperate species. Due to the lack of synapomorphies, the relationships of some species cannot be reliably determined on the basis of external morphological characters alone. |
