Why is Hellmayr also author of Nonnula ruficapilla nattereri? I thought as Hartert read the article he is the only author? Of course both are mentioned in the name of the subspecies. But I remember similar cases whith one author only.

Just if anyone is interested. Thank's to Laurent:

There is in fact no rule at all that associates reading to authorship --
not even co-authorship. (If, say, Hartert had read a text unambiguously
attributed to Hellmayr alone, this text being read by Hartert would not
have changed its authorship.)

Yet, minutes and meeting reports can be extremely blurry in terms of
authorship, for several reasons. E.g., in the present case:
- The author(s) of *the description* is/are in fact not identified at
all. (We are given (1) the name of a reader, and (2) the names of two
persons responsible for the name; neither *needs to* be identical to the
author(s) of the descriptive text.)
- Note that Hartert is talked of in the third person in the last
paragraph of the text ("Hartert has compared the specimen collected by
Natterer" [etc.]); this suggests the printed text was different from the
text that was actually read -- possibly paraphrased / rewritten by a
third person acting as an editor.

The Code has this:

50.2. Authorship of names in reports of meetings. If the name of a taxon
is made available by publication in a report or minutes of a meeting,
the person responsible for the name, not the Secretary or other reporter
of the meeting, is the author of the name.

IOW: Better not to bother about all these issues. Just try to identify
who, in the minutes/report, appears responsible for the name and go with
this.
 
Small-headed Elaenia - what a brilliantly ugly name; my vote is for Sordid Elaenia - only another 99,999 votes and it can be discussed in Parliament (an equally pointless organisation).
 
Mionectes rufiventris

Mascarenhas, R., Miyaki, C.Y., Dobrovolski, R. et al. Late Pleistocene climate change shapes population divergence of an Atlantic Forest passerine: a model-based phylogeographic hypothesis test. J Ornithol (2019). https://doi.org/10.1007/s10336-019-01650-1

Abstract:

Several evolutionary processes seem to have influenced the Atlantic Forest (AF) biogeographic history, as suggested by phylogeographic studies that have shown a multitude of patterns. Here, we use approximate Bayesian computation to test alternative historical hypotheses to investigate the phylogeographic pattern, historical demography, and palaeodistribution of the Grey-hooded Flycatcher Mionectes rufiventris, an endemic AF bird, distributed mainly in southern areas of the biome. Our goal was to integrate molecular and ecological data to test diversification hypotheses available for the AF. Our investigation revealed two mitochondrial phylogroups, geographically structured around the Doce River. Coalescence analyses revealed that these groups shared a common ancestor in the Late Pleistocene, between 200,000 and 300,000 years ago, and that divergence was probably associated with climatic fluctuations during this period. Demographic analyses suggested recent demographic expansion in both groups. Ecological niche modelling suggested larger ranges during the Last Glacial Maximum (LGM) than in the present, not in agreement with the genetic pattern recovered. We simulated alternative historical models to test these competing scenarios. Our findings support the existence of small populations during the LGM which expanded afterwards from putative refuges. Thus, these results suggest that the Pleistocene climate shaped patterns of diversification and demographic history of this species in accordance with the classical forest refuge hypothesis.
 
IOC split this into 3 species (+ a 4th extinct) a couple of years ago - is this the same, or even more splitting?

I am not sure if IOC split the "Austral migrant rubinus" from other mainland groups? That would leave for the rest of the mainland groups: "However, P. obscurus would include: obscurus, piurae, ardens, cocachacrae, saturatus, mexicanus, blatteus, flammeus and pinicola."

Voting is set up as stepwise, so not all splits will necessarily happen even if some are.

Merge the monotypic genus Nesotriccus into Phaeomyias, as species Phaeomyias ridgwayi. Zucker et al. (2016) found this species nested within Phaeomyias murina. The authors propose splitting P. murina into three species. Setting aside the problem of species limits, maintenance of a monotypic genus for this taxon is incompatible with their results.

Once again, Nesotriccus has priority over Phaeomyias, Great Scott! Mister Remsen, please
