Trochilini is one of the threetribes that make up thesubfamilyTrochilinae in the hummingbirdfamilyTrochilidae. The other two tribes in the subfamily areLampornithini (mountain gems) andMellisugini (bees).
The informal name "emeralds" has been proposed for this group. Several genera contain species with "emerald" in their common name includingChlorostilbon which contains ten. The tribe contains 114 species divided into 36 genera.[1][2]
Amolecular phylogenetic study of the hummingbirds published in 2007 found that the species formed nine majorclades.[3] WhenEdward Dickinson andJames Van Remsen, Jr. updated theHoward and Moore Complete Checklist of the Birds of the World for the 4th edition in 2013 they based their classification on these results and placed three of the nine clades in thesubfamilyTrochilinae. The clades were placed in separatetribes which they named Trochilini (emeralds),Lampornithini (mountain gems) andMellisugini (bees).[4] The tribe Trochilini with the current circumscription was introduced in 2009.[5]
Molecular phylogenetic studies by Jimmy McGuire and collaborators published between 2007 and 2014 determined the relationships between the major groups of hummingbirds.[1][3][5] In thecladogram below the English names are those introduced in 1997.[6] The Latin names are those proposed by Dickinson and Remsen in 2013.[7]

The 2014 study by McGuire led to a major revision of the classification of the Trochilini.[1] Many of the traditional genera were found to bepolyphyletic and as a result the classification was substantially revised as shown below in thecladogram. Only one new genus was introduced (Elliotomyia) but eleven genera were resurrected (Phaeoptila,Riccordia,Pampa,Thaumasius,Talaphorus,Leucolia which was later renamedRamosomyia,Saucerottia,Amazilis,Uranomitra,Chionomesa andPolyerata). At the same time six of the former genera weresynonymized (Aphantochroa,Cyanophaia,Elvira,Goethalsia,Juliamyia andLepidopyga).[2][8]
