Higher-level phylogeny and morphological evolution of tyrant flycatchers, cotingas, manakins, and their allies (Aves: Tyrannida)
چکیده انگلیسی

Despite increased understanding of higher-level relationships in passerine birds in the last 15 years, the taxonomic boundaries and phylogenetic interrelationships of the major groups of the Tyrannida (including the cotingas, manakins, tityrines, and tyrant flycatchers) remain unclear. Here, we present an analysis of DNA sequence data obtained from two nuclear exons, three introns, and one mitochondrial gene for 26 genera of Tyrannida and 6 tracheophone outgroups. The analysis resulted in well-supported hypotheses about the earliest evolution within Tyrannida. The Cotingidae, Pipridae, Tityrinae (sensu) [Prum, R.O., Rice, N.H., Mobley, J.A., Dimmick, W.W., 2000. A preliminary phylogenetic hypothesis for the cotingas (Cotingidae) based on mitochondrial DNA. Auk 117, 236–241], Tyrannidae, and the tyrannid subfamiles Tyranninae and Pipromorphinae (sensu) [Sibley, C.G., Monroe, B. L. Jr., 1990. Distribution and Taxonomy of Birds of the World. Yale University Press, New Haven, CT] were all found to be reciprocally monophyletic (given the present taxon sampling). The Cotingidae and Pipridae form a clade that is the sister group to a well-supported clade including Oxyruncus, the Tityrinae, Piprites, and the Tyrannidae. Oxyruncus is the sister group to the Tityrinae, and Piprites is placed as the sister group to the Tyrannidae. The tyrannid subfamilies Tyranninae and Pipromorphinae are monophyletic sister taxa, but the relationships of Platyrinchus mystaceus to these two clades remains ambiguous. The presence of medial (= internal) cartilages in the syrinx is a synapomorphy for the Oxyruncus–Tityrinae–Piprites–Tyrannidae clade. Although morphological synapomorphies currently support the monophyly of both the Pipridae and the Cotingidae, convergences and/or reversals in morphological character states are common in Tyrannida. The relationship between Oxyruncus and the Tityrinae is congruent with additional syringeal synapomorphies and allozyme distance data. Accordingly, we propose the recognition the family Tityridae within the Tyrannida to include the genera Schiffornis, Laniisoma, Laniocera, Iodopleura, Xenopsaris, Pachyramphus, Tityra, and Oxyruncus.
