16. Merge Pyrrhocoma Cabanis, 1851

(type = Tachyphonus ruficeps Strickland, 1844 , currently Pyrrhocoma ruficeps ), and Hemispingus superciliaris Cabanis, 1851 (type = Arremon superciliaris Lafresnaye, 1840 ), into Thlypopsis Cabanis, 1851 (type = Nemosia fulvescens Strickland, 1844 , a junior synonym of Nemosia sordida d’Orbigny & Lafresnaye, 1837, currently Thlypopsis sordida ) ( Fig. 3 ). For H. superciliaris , the name becomes Thlypopsis superciliaris ; see below for a new name for Pyrrhocoma .

Comments. Hemispingus superciliaris and the sole species of Pyrrhocoma are embedded within a strongly supported clade (PP = 1.0, ML bootstrap = 80) containing all six species of Thlypopsis . The type species of each of these three genera are contained within this clade. Therefore, maintaining all three names would require naming several additional new genera. Instead, we recommend merging all the species in this clade into a single genus. All three genera were proposed simultaneously in the same publication. Because most of the species in this clade belong to Thlypopsis , we act as first revisers in selecting Thlypopsis Cabanis, 1851 , to take precedence over Pyrrhocoma Cabanis, 1851 , and Hemispingus Cabanis, 1851 , as the name of this genus. When Pyrrhocoma is merged with Thlypopsis , Pyrrhocoma ruficeps Strickland, 1844 , becomes a junior homonym of Thlypopsis ruficeps d’Orbigny & Lafresnaye, 1837. Therefore, we introduce the following replacement name for Pyrrhocoma ruficeps when it is included in the genus Thlypopsis :
