The phylogenetic relationships of trogons were investigated by Espinosa de los Monteros (1998), based on DNA sequence data for two mitochondrial genes (cytochrome b and 12S ribosomal RNA), and by Moyle (2005), using DNA sequence data from both nuclear (RAG-1) and mitochondrial (ND2) genes. Espinosa de los Monteros included only a single species of Priotelus (P. temnurus, Cuban Trogon) in his investigation, whereas Moyle included both species. As expected, Priotelus temnurus and Priotelus roseigaster are sister-species. Espinosa de los Monteros identified Priotelus as basal to a clade of New World trogons (including the genera Trogon, Euptilotis, and Pharomachrus), which is sister to a clade of Old World trogons (Harpactes and Apaloderma). In contrast, Moyle found that Priotelus is near the base of the entire trogon radiation, and is sister to a clade that includes both New World (Trogon) and Old World (Harpactes, Apaloderma) genera.
