Thanks Mark.
Yes Metopothrichinae and Xenerpestinae on this page are definitely nude.
Pipridae and Platyrinchinae in the other pdf would be nude as well if they were new here (which they were not -- Pipridae is either by Rafinesque 1815, if you accept his names, or by Vigors 1825, if you don't; Platyrinchinae is in my opinion by Sundevall 1836). The attached words are not a statement of characters. A statement about the circumscription of a family-group taxon, the inclusion/exclusion of this or that genus, or the general sharpness of the boundary of the taxon, does not make a name available if no actual characters are mentioned.

Platyrinchinae = Platyrhynchides Sundevall 1836.

Berlepsch (1907: 482) recognized Ihering's Euscarthminae,
although calling it Platyrinchinae, but extracted from it three genera for which he
created a new subfamily, Rhynchocyclinae. It was the latter family, to which was
added Platyrinchus that became Hellmayr's Platyrinchinae 1925. Melvin Traylor Jr.1977.

I'm glad I used the neutral term added words and did not call them a description.

In fact, Freeman and Montgomery (2017) did not analyze voice, they showed a different response in playback experiments. Vocal differences have been described elsewhere prior to these playback experiments.

Abstract
Dendrocincla woodcreepers are ant-following birds widespread throughout tropical America. Species in the genus are widely distributed and show little phenotypic variation. Notwithstanding, several subspecies have been described, but the validity of some of these taxa and the boundaries among them have been discussed for decades. Recent genetic evidence based on limited sampling has pointed to the paraphyly of D. fuliginosa, showing that its subspecies constitute a complex that also includes D. anabatina and D. turdina. In this study we sequenced nuclear and mitochondrial markers for over two hundred individuals belonging to the D. fuliginosa complex to recover phylogenetic relationships, describe intraspecific genetic diversity and provide historical biogeographic scenarios of diversification. Our results corroborate the paraphyly of D. fuliginosa, with D. turdina and D. anabatina nested within its recognized subspecies. Recovered genetic lineages roughly match the distributions of described subspecies and congruence among phylogenetic structure, phenotypic diagnosis and distribution limits were used to discuss current systematics and taxonomy within the complex, with special attention to Northern South America. Our data suggest the origin of the complex in western Amazonia, associated with the establishment of upland forests in the area during the early Pliocene. Paleoclimatic cycles and river rearrangements during the Pleistocene could have, at different times, both facilitated dispersal across large Amazonian rivers and the Andes and isolated populations, likely playing an important role in differentiation of extant species. Previously described hybridization in the headwaters of the Tapajós river represents a secondary contact of non-sister lineages that cannot be used to test the role of the river as primary source of diversification. Based on comparisons of D. fuliginosa with closely related understory upland forest taxa, we suggest that differential habitat use could influence diversification processes in a historically changing landscape, and should be considered for proposing general mechanisms of diversification.

Is Geobates Swainson, 1837, an available name, and if yes, what's its type species ?

R. I. G. states that the binomial name Geobates brevicauda Swain. (current synonym?) is a nomen nudum. I've been split Geositta into two genera Geositta and Geobamon because I have a doubt about the nomenclatural status of Geobates.

Abstract:

The incidence of introgression during the diversification process and the timespan following divergence when introgression is possible are poorly understood in the Neotropics where high species richness could provide extensive opportunities for genetic exchange. We used thousands of genome‐wide SNPs to infer phylogenetic relationships, calculate ages of splitting, and to estimate the timing of introgression in a widespread avian Neotropical genus of woodcreepers. Five distinct introgression events were reconstructed involving taxa classified both as subspecies and species including lineages descending from the basal–most split, dated to 7.3 million years ago. Introgression occurred between just a few hundred thousand to about 2.5 million years following divergence, suggesting substantial portions of the genome are capable of introgressing across taxa boundaries during a protracted time window of a few million years following divergence when reproductive isolation is incomplete and introgression is possible. Despite this protracted time window, we found that the proportion of the genome introgressing (6 to 11%) declines with the time of introgression following divergence, suggesting that the genome becomes progressively more immune to introgression as reproductive isolation increases.

The identity of Azara´s (1805) No. 246 Trepador remos y cola roxos (Aves: Furnariidae)
PAUL SMITH

Zootaxa Vol 4766, No 4 (22 April 2020)

Abstract

The identity of Azara’s No. 246 “Trepador remos y cola roxos” and the names Dendrocolaptes miniatus Illiger, 1820 and Dendrocopus rubricaudatus Vieillot, 1818, which are based on it, have never been convincingly elucidated, and previously proposed identifications in the literature are demonstrably incorrect. Azara shot his specimen in a Paraguayan forest and provided a detailed description and measurements of it in his Spanish text. These are sufficient to confirm the identity of the specimen and the names based on it as the Olive Spinetail, long known as Cranioleuca obsoleta (Reichenbach, 1853). Dendrocolaptes miniatus Illiger, 1820 and Dendrocopus rubricaudatus Vieillot, 1818 nevertheless have date priority over that name, but as they have not been used as valid since 1899 they are nomina oblita under Article 23.9.2 of the Code. Cranioleuca obsoleta has been in universal use for this species since Hellmayr (1925), so it qualifies as a nomen protectum under Article 23.9.2, and remains the valid name for the Olive Spinetail.

Dendrocincla fuliginosa, Xenops minutus

Arbeláez-Cortés, Enrique. 2020. Defining the phylogeographic relationship between cis- and trans-Andean populations of Dendrocincla fuliginosa and Xenops minutus in Colombia. Revista Mexicana de Biodiversidade 91: e912984.

http://www.revista.ib.unam.mx/index.php/bio/article/view/2984/2078

Abstract:

Due to the position of Colombia between Central and South America, and the presence of several ecosystems in its territory, phylogeographic information from populations across this country is fundamental to understand the evolutionary history of widespread Neotropical species. The Andes have long been noted for their influence isolating lowland species into cis- and trans-Andean populations. However, detailed sampling across cis-Andean zones adjacent to the Andes (i.e., Orinoquia) has been lacking in avian phylogeographic studies. Information from DNA sequences, from 2 passerine birds: Dendrocincla fuliginosa and Xenops minutus is presented herein; to depict their phylogeographic patterns, focusing on the relationship between cis- and trans-Andean populations from Colombia. The analyses, regarding Colombian samples indicated that cis-Andean populations (i.e., Orinoquia and Amazon) are not closely related, rather the Orinoquia populations are more closely related to trans-Andean populations in both species. These relationships suggest that populations on both sides of the Andes were connected in the recent past (less than 1 myA). I propose that phylogeographic differentiation in lowland species in this region is not only explained by the presence of the Andean mountains, but also based on the ecological shifts between major ecosystems such as Amazonia and Orinoquia.

Abstract:

How wide is the time window for introgression after divergence? Pulido‐Santacruz et al. addressed this question by studying the evolutionary history of the bird genus Dendrocincla. They found five introgression events that occurred between a few hundred thousand and around 2.5 million years after divergence. The introgressed genomic proportion declined exponentially with the age of the hybridizing taxa. Hence, this study suggests that species boundaries are permeable up to 2.5 million years after divergence.

RELICT HUMID TROPICAL FOREST IN MEXICO PROMOTES DIFFERENTIATION IN BARRED WOODCREEPERS Dendrocolaptes (AVES: FURNARIIDAE)
ADOLFO G. NAVARRO-SIGÜENZA, R. CARLOS ALMAZÁN-NÚÑEZ, L. ENRIQUE SÁNCHEZ-RAMOS, M. FANNY REBÓN-GALLARDO, ENRIQUE ARBELÁEZ-CORTÉS

Abstract

Humid tropical forests in Mesoamerica are distributed along the Atlantic slope and, in scattered locations, along the Mexican Pacific slope. These poorly explored Mexican forests include microendemic bird species. Two species in the genus Dendrocolaptes occur in lowland and foothill humid tropical forests of Mesoamerica. One of these, D. sanctithomae, is comprised of four subspecies, of which the two that occur in Mexico, D. s. sanctithomae and D. s. sheffleri, are distinctly different morphologically, and the latter is a poorly known microendemic taxon of the Mexican Pacific humid tropical forest in the Sierra Madre del Sur. We used both nuclear (nDNA) and mitochondrial DNA (mtDNA) to evaluate the genetic variation of D. sanctithomae in Mexico, and complemented this with a quantitative analysis of phenotypic traits. We also conducted analyses of environmental niche models to test the hypothesis of niche differentiation of D. s. sheffleri from other taxa of D. sanctithomae. Our phylogenetic reconstructions of mtDNA consistently recovered D. s. sheffleri and D. s. sanctithomae as reciprocally monophyletic, while they shared alleles of nDNA. These mtDNA differences are comparable with differences reported between other Dendrocolaptes sister-taxa pairs. Our analysis of phenotypic traits also indicated that the taxa differ in measurements of hallux and feather barring. In contrast, niche differentiation tests suggest that the niches of both taxa are more similar than expected by chance. Our evidence leads us to propose species status for D. sheffleri. This is an additional example of recent speciation in Mexico that indicates active and peripatric evolutionary differentiation in the northern Neotropics.

In addition to the Rufous Antpitta tick-fest, this also came out today (open access): https://onlinelibrary.wiley.com/doi/epdf/10.1111/jzs.12408

It provides more support for many of the Amazonian Barred-Woodcreeper splits proposed in the HBW17 volume, and which were not accepted by SACC. It recommends at least one split from what is currently Black-banded Woodcreeper, with others awaiting more molecular data.

Some other trans-Andean taxa that have been proposed as splits elsewhere were not evaluated as they did not have samples.

I really need to learn to read a figure because I don't understand how they can to determine that this branch is a species and this one is a subspecies when they are of equal distance. They treat juruanus as a separate species but not costaricensis which seems older. I need more explanation
