- ↑ Herpsilochmus Cabanis, in Wiegmann's Archiv für Naturg., xiii, pt. i, 1847, 224. Type, Myiothera pileata Lichtenstein. — Dendroæcia Bertoni, Aves Nuevas del Paraguay, 1901, 138. Type, D. erythroptera Bertoni = Myiothera rufimarginata Temminck. (Nearly the whole of tropical South America east of the Andes; about eleven species recognized, of which, however, the present writer has examined only four.) I am not able to find any structural characters separating Herpsilochmus from Microrhopias.
- ↑ Formicivora (not Formicivorus Temminck, 1807) Swainson, Zool. Journ., ii, 1825, 145. Type, Myiothera squamata Lichtenstein. — Drymophila Such (ex Swainson), Zool. Journ., i, Jan., 1825, 559. Type, D. variegata Such = Myiothera ferruginea Lichtenstein. — Ellipura Cabanis, in Wiegmann's Archiv für Naturg., xiii, pt. i, 1847, 228. Type, Myiothera ferruginea Lichtenstein. — Stipituropsis Bertoni, Aves Nuevas del Paraguay, 1901, 141. Type, S. arechavaletæ Bertoni = Formicivora genei De Filippi.
- ↑ Thamnomanes Cabanis, in Wiegmann's Archiv für Naturg., xiii, pt. i, 1847, 230. Type, Lanius caesius Lichtenstein. (Colombia and Guiana to southeastern Brazil and upper Amazon Valley; two species.)
- ↑ Pyriglena Cabanis, in Wiegmann's Archiv für Naturg., xiii, pt. i, 1847, 211. Type, Lanius domicella Lichtenstein = Turdus leucopterus Vieillot. (Ecuador and Peru to southeastern Brazil; five species recognized, of which the present writer has examined only P. leucoptera (Vieillot) and P. atra (Swainson).)
- ↑ Myrmoborus Cabanis and Heine, Mus. Hein., ii, July, 1859, 9. Type, Pithys leucophrys Tschudi. Besides the type species, I would refer the following to this genus: M. myiotherinus (Spix) and M. lugubris Cabanis; probably also Hypocnemis schistacca Sclater and H. melanura Sclater and Salvin, and possibly H. melanopogon Sclater, but these three species I have not seen.
