TiF Update August 24
Based on Bravo et al. (2014), Myrmochanes has been submerged into Myrmotherula, and Stymphalornis has been submerged into Formicivora. Epinecrophylla and Myrmotherula have been rearranged. As Myrmopagis proved paraphyletic, it has been divided into Myrmopagis, Myrmopagis2, and Myrmopagis3. Finally, Ihering's Antwren, Myrmopagis iheringi (aka Myrmotherula iheringi) and Narrow-billed Antwren, Formicivora iheringi have been placed in Neorhopias. Since F. iheringi has priority, M. iheringi takes a new name, based on the subspecies heteropterus. This may be split (see Miranda et al., 2013), in which case the new subspecies name oreni would be promoted. Note that N. h. iheringi needs a new name, but it would be at the bottom of the priority list.

Klodiana Jorgii, 2014. A Multiloci Approach to Resolve Deep Relationships in a Major Clade of Thamnophilid Antbirds (Aves: Passeriformes). Long Island University, The Brooklyn Center.
Abstract:
Phylogenies are fundamental to understand the origin and evolution of organisms. With the advent of
molecular phylogenetics, our ability to uncover evolutionary relationships has greatly improved. However,
the accurate reconstruction of relationships using molecular data can still be problematic because gene
trees may not always reflect the species tree. One possible solution is to increase sampling of loci to help
uncovering the species tree. In this study, we use a multiloci approach to resolve basal poorly
supported/ambiguous nodes within a major clade of thamnophilid antbirds (Aves, Thamnophilidae) for
which a conflictive signal between mitochondrial and nuclear markers has been reported (Tello et al.,
2014, Zool. J. Linn. Soc. 170:546-565). Our preliminary results showed that the resulting tree from two
novel nuclear introns (from ACO1 and ALDOB genes) is congruent with the mitochondrial topology,
suggesting that the mitochondrial tree represents the species tree for this major clade of birds.

TiF Update January 27, 2017
Ant-followers: Based on Isler et al. (2014), the phylogeny of Pithyini has been adjusted. Further, the Lunulated Antbird and White-throated Antbird have been moved from Gymnopithys to the new genus Oneillornis (Isler et al., 2014; type lunulatus) to avoid merging Gymnopithys and Rhegmatorhina.
Cool new paper on the Rondonia Bushbird:

Species limits in the genus Thamnistes (Aves: Passeriformes: Thamnophilidae): an evaluation based on vocalizations
MORTON L. ISLER, BRET M. WHITNEY
Abstract
The monotypic genus Thamnistes, consisting of the Russet Antshrike, T. anabatinus, is primarily a resident of foothills forests of the northern Andes and Middle America, extending to adjacent lowlands especially on the Pacific slope. Its vocalizations are somewhat poorly recorded as it is a participant in noisy mixed flocks of the lower canopy to the upper understory. In recent years, however, vocalizations of the Russet Antshrike have been recorded sufficiently to permit geographic analysis. Vocalizations supply valuable measures of species limits for antbirds because they are not learned. Our analysis revealed that the southernmost population was vocally distinct and is more appropriately considered a biological species: T. rufescens (Rufescent Antshrike). An additional population of the Russet Antshrike, T. a. aequatorialis, awaits further evaluation pending the acquisition of additional vocal recordings, morphological study, and genetic analysis.

Calls distinguish species of Antbirds (Aves: Passeriformes: Thamnophilidae) in the genus Pyriglena
MORTON L. ISLER, MARCOS MALDONADO-COELHO
Abstract
Populations in the genus Pyriglena Cabanis, 1847, commonly known as fire-eyes, are patchily distributed in central South America from the Pacific slope of the Andes to the Atlantic Forest of Brazil. Pyriglena populations are currently placed into 12 taxa, only five of which are not isolated from their neighbors by distance, a high mountain range, or a major river. In the Thamnophilidae, taxonomic decisions regarding such allopatric populations have primarily rested on differences in vocalizations, thought not to be learned and to play a key role in the speciation process. When we examined Pyriglena vocalizations in this context, the outcomes revealed substantial diversity in their calls, rather than their songs. They commonly delivered four different types of calls, unusual although not unprecedented in thamnophilids. Diversity in calls rather than songs underscores the need to consider all vocalizations in taxonomic studies. The outcomes support the continued recognition of the White-shouldered Fire-eye Pyriglena leucoptera (Vieillot) and Fringe-backed Fire-eye Pyriglena atra (Swainson) as distinct species, and indicate that, in addition, the currently constituted Pyriglena leuconota should be considered three species: the Western Fire-eye Pyriglena maura (Ménétries); the Tapajos Fire-eye Pyriglena similis Zimmer; and the East Amazonian Fire-eye Pyriglena leuconota (von Spix). We also identify taxonomic uncertainties regarding subspecies that require acquisition of additional data and further analysis.

Andre E. Moncrieff, Oscar Johnson, Daniel F. Lane, Josh R. Beck, Fernando Angulo, and Jesse Fagan (2018) A new species of antbird (Passeriformes: Thamnophilidae) from the Cordillera Azul, San Martín, Peru. The Auk: January 2018, Vol. 135, No. 1, pp. 114-126.
Abstract:
We describe a distinctive new species of antbird (Passeriformes: Thamnophilidae) from humid montane forest (1,340–1,670 m above sea level) of the Cordillera Azul, San Martín Region, Peru. Plumage, voice, and molecular evidence distinguish this species from its sister taxon Myrmoderus ferrugineus (Ferruginous-backed Antbird), which is found in lowland Amazonian rainforests of the Guiana Shield and Madeira-Tapajós interfluvium. The new species is presently known only from one ridge in the Cordillera Azul, and therefore we recommend further fieldwork to better estimate its distribution and population size.
