  <dc:description>&lt;p&gt;&lt;span&gt;Phylogenetic relationships among swifts of the morphologically conservative genus&amp;nbsp;&lt;/span&gt;&lt;i&gt;Chaetura&lt;/i&gt;&lt;span&gt;&amp;nbsp;were studied using&amp;nbsp;mitochondrial&amp;nbsp;and&amp;nbsp;nuclear DNA&amp;nbsp;sequences. Taxon sampling included all species and 21 of 30 taxa (species and subspecies) within&amp;nbsp;&lt;/span&gt;&lt;i&gt;Chaetura&lt;/i&gt;&lt;span&gt;. Our results indicate that&amp;nbsp;&lt;/span&gt;&lt;i&gt;Chaetura&lt;/i&gt;&lt;span&gt;&amp;nbsp;is monophyletic and support the division of the genus into the two subgenera previously identified using plumage characters. However, our genetic data, when considered in combination with phenotypic data, appear to be at odds with the current classification of some species of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Chaetura&lt;/i&gt;&lt;span&gt;. We recommend that&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. viridipennis&lt;/i&gt;&lt;span&gt;, currently generally treated as specifically distinct from&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. chapmani&lt;/i&gt;&lt;span&gt;, be returned to its former status as&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. chapmani viridipennis&lt;/i&gt;&lt;span&gt;, and that&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. andrei&lt;/i&gt;&lt;span&gt;, now generally regarded as synonymous with&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. vauxi aphanes&lt;/i&gt;&lt;span&gt;, again be recognized as a valid species. Widespread Neotropical species&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. spinicaudus&lt;/i&gt;&lt;span&gt;&amp;nbsp;is paraphyletic with respect to more range-restricted species&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. fumosa&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. egregia&lt;/i&gt;&lt;span&gt;, and&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. martinica&lt;/i&gt;&lt;span&gt;. Geographically structured genetic variation within some other species of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Chaetura&lt;/i&gt;&lt;span&gt;, especially notable in&amp;nbsp;&lt;/span&gt;&lt;i&gt;C. cinereiventris&lt;/i&gt;&lt;span&gt;, suggests that future study may lead to recognition of additional species in this genus. Biogeographic analysis indicated that&amp;nbsp;&lt;/span&gt;&lt;i&gt;Chaetura&lt;/i&gt;&lt;span&gt;&amp;nbsp;originated in South America and identified several dispersal events to Middle and North America following the formation of the Isthmus of Panama.&lt;/span&gt;&lt;/p&gt;</dc:description>
