Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A comprehensive molecular phylogeny of the family Thamnophilidae indicated that the widespread neotropical genus <italic>Cercomacra</italic> Sclater, 1858 is polyphyletic. Two non‐sister clades in putative <italic>Cercomacra</italic> were uncovered: (1) the '<italic>nigricans</italic>' clade (<italic>Cercomacra sensu stricto</italic>), formed by <italic>manu</italic>, <italic>brasiliana</italic>, <italic>cinerascens</italic>, <italic>melanaria</italic>, <italic>ferdinandi</italic>, <italic>carbonaria</italic>, and <italic>nigricans</italic>; and (2) the '<italic>tyrannina</italic>' clade formed by <italic>nigrescens</italic>, <italic>laeta</italic>, <italic>parkeri</italic>, <italic>tyrannina</italic>, and <italic>serva</italic>. <italic>Sciaphylax</italic> was sister to the '<italic>tyrannina</italic>' clade and this group was sister to a clade formed by <italic>Drymophila</italic> and <italic>Hypocnemis</italic>. This whole major clade then was sister to <italic>Cercomacra sensu stricto</italic>. Further work is needed to resolve the phylogenetic placement of <italic>brasiliana</italic> and <italic>cinerascens</italic> within <italic>Cercomacra</italic>, and the relationships within the '<italic>tyrannina</italic>' clade. Because the group of species referred to as the '<italic>tyrannina</italic>' clade does not have an available name, we erect a new genus that recognizes the monophyly and distinct nature of this group. A molecular time scale for the evolution within <italic>Cercomacra sensu lato</italic> is proposed. © 2014 The Linnean Society of London</p> </abstract>
