Cyanoderma erythropterum, Mixornis gularis
Emilie Cros, Frank E Rheindt. Patterns of diversification in two babbler species from Sundaland. Society for Molecular Biology and Evolution Conference 2016.
Abstract:
Pleistocene climate fluctuations are known to be an important driving force in biological differentiation. Despite Sundaland’s high levels of biodiversity and the important impact Pleistocene climate fluctuations have had on Sundaic landmass connectivity and topography, studies of the impact of those fluctuations on differentiation in Sundaic species are scarce. Recent studies have shown complex patterns of bioacoustics and genetic variation among bird populations of different landmasses in Sundaland, suggesting that some of those populations may in fact no longer experience gene flow between one another despite recurrent land bridges connecting their ranges. Babblers (Timaliidae) are highly sedentary denizens of the undergrowth of Southeast Asian rainforests in which great regional bioacoustic variation has previously been reported. As such, they are an ideal model to study the mechanisms that have led to biological differentiation across Sundaland. Here, we use genome-wide sequence data to assess patterns of diversification and gene flow among populations from different parts of the Sundaic region. Pleistocene climate fluctuations may have affected population connectivity differently depending on species ecology. We therefore conducted a comparison between a forest-dependent babbler complex (Cyanoderma erythropterum) and an edge-tolerant babbler complex (Mixornis gularis).

Tit-babblers
Cros E. & Rheindt F.E., in press. Massive bioacoustic analysis suggests introgression across Pleistocene land bridges in Mixornis tit-babblers. J. Orn.
Abstract Because of complex patterns of Pleistocene land connections across its land masses, the Sundaic region is particularly interesting for studying the mechanisms of biological differentiation. Using an unusually large bioacoustic dataset, we studied patterns of vocal differentiation among populations of the widespread Striped Tit-Babbler Mixornis gularis complex. We demonstrate diagnostic differences in song characteristics between distant populations found on separate landmasses, but we show that these differences emerge as clinal once populations on small, rarely-sampled and geographically intermediate islands are included in the analysis. This pattern suggests bioacoustic clinality among different island members of the complex in contrast to results from previous morphological research. Our vocal data additionally uncover cases of potential erroneous taxon attribution and confirm cases of suggested synonymizations in this complicated species complex. Our study supports calls for the integration of bioacoustic data in evolutionary research and underscores the importance of extensive taxon sampling, especially in archipalegic settings such as Sundaland where numerous geographically intermediate island populations may serve as conduits for gene flow during Pleistocene drops in sea level.

Jabouilleia naungmungensis
Swen C. Renner, John H. Rappole, Myint Kyaw, Chris M. Milensky & Martin Päckert. Genetic confirmation of the species status of Jabouilleia naungmungensis. Journal of Ornithology. First Online: 04 September 2017.
Abstract:
Species assessment of allopatric taxa is problematic. Here we consider the case of the Naung Mung Scimitar Babbler (Jabouilleia naungmungensis) from northern Myanmar. This bird was recognized as a new species in its original description, but was subsequently considered to be a subspecies of J. danjoui. We review the procedures used to make this assessment, and consider them in light of morphological (significantly different bill and hallux claw lengths) and new genetic (7.0% genetic distance, cytochrome b) information. Based on this reconsideration, taking acoustic information into account, we conclude that the data unequivocally confirm the recognition of J. naungmungensis as a full species.

Pellorneidae: Trichastoma [Pellorneum] celebense
Three new sub-species of Sulawesi Babblers have been discovered?!
My final year thesis was a phylogenetic reassessment of the Sulawesi Babbler (Trichastoma celebense). Like many birds from this area of Indonesia, this species has been poorly studied. This project was prompted by evidence of song divergence of the Babblers from the island of Kabaena (noticed by Dr. David Kelly and Prof. Nicola Marples). In birds, song divergence is one of the first signs of a species diverging. In order to investigate the taxonomy of Sulawesi Babblers we extracted DNA from the feathers of Sulawesi Babblers from different islands of Sulawesi and created a phylogeny using the mitochondrial ND3 gene. These analyses provided evidence of cryptic diversity within Sulawesi Babblers in SE Sulawesi. We discovered that Trichastoma celebense rufofuscum might contain up to three unrecognised subspecies! However, further analyses of barcoding genes would be required before revisions to the taxonomy of the Sulawesi Babblers are made. Hopefully these findings will highlight cryptic biodiversity in Sulawesi’s fauna and encourage researchers to investigate other species.

But the original spelling of this appears to be Schaeniparus, not 'Schoeniparus'. OD: https://biodiversitylibrary.org/page/29846830
Neave had it correct.
The Richmond Index also started with -ae-, but was then 'corrected' to -oe-.

Yes, this (Sharpe & Murie 1876 designating Proparus dubium Hume 1874) seems to be the correct type fixation. I suspect the name is currently in use based on the fixation suggested on the Richmond card, and that was also accepted in the Peters Check-list (https://biodiversitylibrary.org/page/14486586 ): designation by Sharpe 1883:606 (https://biodiversitylibrary.org/page/8301318 ) of Minla rufogularis Mandelli 1873; but that was 7 years later and has no standing. (And I actually don't read the OD as having included that species...
But it's admittedly not really clear.) Fortunately, switching form Minla rufogularis Mandelli to Proparus dubius Hume does not affect the applicability of the generic name under the current phylogenetic hypotheses.

As far as I can tell looking closely at Hume's Stray Feathers (1874), Hume used the same ligature (in text) in, for example, "Cyornis Tickellidæ" (on p.405). Also compare with the ligature he used (on p.329) for Drymœca (oe). It´s very similar, but not the same.
In this cut the œ (oe) is a tiny bit more rounded, and it lacks the "blob" in the top middle, seen in the slightly (somewhat) more compressed æ (ae). It´s not the best ligature version (of æ/ae) ... but still, that´s the one he used.
Does this mean we (necessarily?) ought to use Schaeniparus, instead of the widely, since long, all over, used Schoeniparus ... ?!?
Björn
PS. I wish that Hume had used the ligature he did use in the (bold) heading of "Cyornis Tickellidæ". Far less easy to miss ... Compare the excerpts below.

...Depends how you read the Code and its "prevailing use" provisions...
(If you follow the recommendations of David & Dickinson 2016 [pdf], addressing similar issues in Vieillot's work, we should use it. "Schaen-" is admittedly a bad latinization of σχοιν- (rush), but bad latinization of Greek words is not supposed to be correctable in the Code... But of course this discards all considerations of prevailing use as inapplicable.)
I wouldn't say the name is in such wide use in the published literature, actually -- it has been almost universally treated as invalid for most of the last decades. E.g., searching Google Books for it in works from the last 50 years (1968 onwards) produces less than 20 hits; and these include things like the Eponym dictionary of birds, the Helm dictionary of scientific bird names, as well as works that only cite it as a synonym or in original combinations without using it as valid.

Laurent, a common Google seach gives me 3400 results for Schoeniparus, but only 27 for Schaeniparus ... a Google Book search results in 606 versus 36, Avibase uses Schoeniparus, as well as eBird/Clements (2018), and onwards, ... which I think would qualify for the phrase "widely" used.
However; luckily for me, in Sweden we follow IOC, thereby they´re placed in Alcippe, and as such I can simply leave the usage of œ/æ, without any comments what-so-ever...
This one I gladly leave in the hands of the taxonomists concerned ...

The genus Pomatorhinus bears this name because the nostrils have an operculum. Is this characteristic carried by genera Erythrogenys, Melanocichla and Stachyris, the most closely related genera ?

Again a question on authorship and perhaps the year of publication. It I unsderstood correct Mixornis gularis ticehursti was published in https://onlinelibrary.wiley.com/doi/epdf/10.1002/mmnz.19390240201 (I haven't seen)
First why is it always claimed published in 1940 and/or where is claimed that this was published in 1940? As well why Gerd Heinrich no co-author (but might be clear within p. 153 which I haven't seen)?

I cannot find it online. But on Zoonomen :
Mitteilungen aus dem Zoologischen Museum in Berlin
[It appears that this serial was issued in Hefte, and that some
volumes spanned more than one year.
Collocallia esculente minuta Stresemann is dated Dec. 1925 in Heft 1
of Vol. 12, other taxa are dated 1926 from later portions of the same volume].
"24. Band 2. Heft" of volume for 1939
has at the foot of the Heft title page
"Ausgegeben am 18. Januar 1940"
[Thanks to Edward C. Dickinson for a scan of the relevant pages to demonstrate this.]

- The authority for this taxon is cited to Stresemann alone by some authors, and to Stresemann and Heinrich by some authors.
- Examination of the paper itself will be necessary to determine which is correct.
