Fluvicolinae is a subfamily of passerine birds in the tyrant flycatcher family Tyrannidae, encompassing species widely distributed across the Americas. The subfamily includes 130 species that are divided into five tribes and 39 genera.
Taxonomy Broad studies in molecular genetics performed by Tello et al. (2009) discovered a large number of new relationships within the family Tyrannidae that were not reflected in the majority of species classified as part of the family. Following these studies, Ohlson et al. (2013) proposed a reorganization and division of the family Tyrannidae, which according to the proposal would divide the family into the subfamilies Fluvicolinae, Hirundineinae Tello, Moyle, Marchese & Cracraft, 2009, Muscigrallinae Ohlson, Irestedt, Ericson & Fjeldså, 2013, Tyranninae Vigors, 1825 and Elaeniinae, Cabanis & Heine, 1859–60.
The cladogram below is based on a large molecular phylogentic study of the suboscines by Michael Harvey and collaborators that was published in 2020. A high resolution version of the phylogenetic tree in Figure 1 is available from the first author's website here. The taxonomy follows the list of world birds maintained by Frank Gill, Pamela C. Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC). The tribes are those proposed by Jan Ohlson and collaborators in 2020 other than the genus Muscigralla that is placed in the tribe Muscigrallini rather than a separate subfamily Muscigrallinae.
Tribes and genera The subfamily is grouped into the following 5 tribes and 39 genera:
