Abstract

...The Asiatic Harpactes lineage formed the sister clade to the
New World trogons, while the African Apaloderma was the
most basal genus and sister to the former two genera
combined. Within the New World clade, quetzals (Pharomachrus
spp.) + Euptilotis neoxenus were located at the
base as sister to the other two genera (Priotelus and
Trogon). The core of the phylogeny was formed by the
genus Trogon. This genus was divided in three subclades...
