Abstract: Two species of
Suiriri (Aves: Tyrannidae) inhabit semi‐open habitats in South America: the polytypic Suiriri Flycatcher (S. suiriri ) and the monotypic Chapada Flycatcher (S. affinis ). The phylogenetic relationship between these congeneric species has never been investigated in detail. Here we used molecular tools—three nuclear introns and two mitochondrial genes—to investigate the systematic position of the Chapada Flycatcher, comparing the results found with morphological and behavioral data. We found that the polytypic Suiriri Flycatcher to be monophyletic and that it is included in a clade of Elaeniini flycatchers includingPhyllomyias, Phaeomyias, andCapsiempis among other genera. The Chapada Flycatcher, on the other hand, is a member of the Fluvicolini, sister toSublegatus , and should be allocated on its own monospecific genus, which we herein describe. We suggest that social mimicry is responsible for the remarkable convergence in size, shape, plumage coloration, and behavior in the adults of the Suiriri Flycatcher and the Chapada Flycatcher.
