Priority of Geranoaetus Kaup, 1844 over Tachytriorchis Kaup, 1844 (Aves: Accipitridae) based on the first reviser principle

摘要: The generic name Geranoaetus Kaup, 1844 (type species: Falco aguia Temminck = Spizaetus melanoleucus Vieillot) generally has been applied only to its type species, G. , although inclusion of fossil species in the genus has been suggested (Wetmore 1933; Amadon 1963). Although is still recognized by some authors (e.g., Thiollay 1994; Remsen et al. 2010), others consider it a junior synonym Buteo Lacepede, 1799, because similarities that (e.g., Wetmore Hellmayr & Conover 1949; Clark 2006). Recent studies molecular phylogenetics buteonine hawks (Riesing 2003; Lerner 2008; Amaral 2006, 2009) unanimously agree on lack monophyly three genera, namely Leucopternis 1847 and  Buteogallus Lesson, 1830, as currently (Remsen 2010).
