Interesting they use Abrornis rather than Phylloscopus.

What is correct?

Phylloscopus poliocephalus becki as in HBW alive

https://www.hbw.com/species/island-leaf-warbler-phylloscopus-poliocephalus

or

Phylloscopus maforensis becki as in BBOC 139(4)?

https://bioone.org/journals/Bulleti...cluding-the/10.25226/bboc.v139i4.2019.a2.full

Numor Leaf Warbler is now Phylloscopus maforensis and is monotypic, so neither of the above are current

 

[sicklebill]

In more detail from HBWAlive: In past, when regulalry lumped, the expanded species was erroneously listed in HBW and elsewhere as P. poliocephalus, but name maforensis has priority. Monotypic.
Distribution:
Numfor I, in Geelvink Bay (NW New Guinea).

 

[l_raty]

so neither of the above are current

Phylloscopus maforensis becki is 'current' H&M / Clements treatment.

HBW/BLI split Phylloscopus maforensis (Gerygone maforensis Meyer 1874 https://biodiversitylibrary.org/page/8663314 ) and Phylloscopus misoriensis (Phylloscopus trivirgatus misoriensis Meise 1931 https://biodiversitylibrary.org/page/3434733 ), as two distinct monotypic spp. The oldest potentially valid species-group name applying to the rest of the complex is then Gerygone poliocephala Salvadori 1876 https://biodiversitylibrary.org/page/34621409: under this taxonomy, Phylloscopus poliocephalus becki is correct.
This is the name adopted for the ssp in the published HBW/BLI illustrated checklist, and is still the implied 'current' name in the HBW/BLI spreadsheet (which omits to list subspecies).

IOC are still using the same taxonomy as H&M and Clements on their website and in their last spreadsheets (v9.2), but they should now in principle move towards adopting the HBW/BLI treatment.

(DeCicco et al 2019 (Bull. Brit. Ornithol. Cl., 139: 311-319) explicitly followed IOC v9.2.)

... the HBW/BLI spreadsheet (which omits to list subspecies)..

It's unfortunate that they don't list the subspecies which make up each of the species in their database and spreadsheet. It's true that a list of subspecies would be mostly irrelevant to BLI's purpose, but it does lead to questions like "what does BLI mean by Phylloscopus maforensis?"

It's possible to follow the link from the spreadsheet to their website and look at the range maps there, but in the past I have sometimes failed to match their range maps with the subspecies range descriptions from e.g. IOC.

So is HBWalive the only reason you say the following?

Numor Leaf Warbler is now Phylloscopus maforensis and is monotypic, so neither of the above are current

I am not sure why they should be moving towards the HBW treatment?

Because they have announced that they accepted the very same splits, see #57 above.

(Which I assumed was also the reason for Phil's (sicklebill's) comment.)

_______

Also, see [here]

AS 10.1
Numfor Leaf Warbler Phylloscopus maforensis
Island Leaf Warbler P. poliocephalus
Morphologically distinct; genetics desired (Beehler & Pratt 2016, HBW). Alström et al. 2018 sampled subspecies pallescens from Kolombangara I (w Solomons). Restore poliocephalus.

AS 10.1
Biak Leaf Warbler Phylloscopus misoriensis

Ok, I read your post as saying they were moving that way in general as opposed to in this particular example. That is why I asked.

Here's an example which I just encountered: Bulbuls in the genus Iole. Both Clements and IOC include the subspecies cinnamomeoventris in Iole viridescens, Olive Bulbul. Whereas HBW includes it in Iole propinqua, Grey-eyed Bulbul, according the HBW Alive website.

BLI follows HBW in this regard, but it doesn't tell you that. If you look at its range maps for Iole viridescens and Iole propinqua on the BLI website and compare them to the range descriptions from the Clements and IOC spreadsheet, if you squint carefully for long enough you can confirm it, though.

But it's possible you might not even think to ask the question. I didn't, until I stumbled over it earlier today.

Abstract
The Sulawesi Subregion was traditionally thought to be home to a single, resident Phylloscopus leaf warbler. However, recent exploration has revealed an additional three species, two of which have only very recently been described: Taliabu Leaf Warbler Phylloscopus emilsalimi and Peleng Leaf Warbler P. suaramerdu from the outlying islands of Taliabu and Peleng, respectively. The third, ‘Selayar Leaf Warbler’, remains undescribed, but here we provide the first bioacoustical documentation of its unique song, along with recommending that Sulawesi Leaf Warbler P. sarasinorum sensu lato should be regarded as two species: Lompobattang Leaf Warbler P. sarasinorum and Sulawesi Leaf Warbler P. nesophilus, based on distinct bioacoustics and morphology.

Cool news. I treat this species as valid based on I don't know which study under the temporary name "Pouillot nésophile".
I was quietly waiting for a new study confirms its status.

Most genomic loci misrepresent the phylogeny of an avian radiation because of ancient gene flow
Systematic Biology (advance online publication)
doi: 10.1093/sysbio/syab024

Phylogenetic trees based on genome-wide sequence data may not always represent the true evolutionary history for a variety of reasons. One process that can lead to incorrect reconstruction of species phylogenies is gene flow, especially if interspecific gene flow has affected large parts of the genome. We investigated phylogenetic relationships within a clade comprising eight species of passerine birds (Phylloscopidae, Phylloscopus, leaf warblers) using one de novo genome assembly and 78 resequenced genomes. On the basis of hypothesis-exclusion trials based on D-statistics, phylogenetic network analysis and demographic inference analysis, we identified ancient gene flow affecting large parts of the genome between one species and the ancestral lineage of a sister species pair. This ancient gene flow consistently caused erroneous reconstruction of the phylogeny when using large amounts of genome-wide sequence data. In contrast, the true relationships were captured when smaller parts of the genome were analyzed, showing that the “winner-takes-all democratic majority tree” is not necessarily the true species tree. Under this condition, smaller amounts of data may sometimes avoid the effects of gene flow due to stochastic sampling, as hidden reticulation histories are more likely to emerge from the use of larger datasets, especially whole-genome datasets. In addition, we also found that genomic regions affected by ancient gene flow generally exhibited higher genomic differentiation but a lower recombination rate and nucleotide diversity. Our study highlights the importance of considering reticulation in phylogenetic reconstructions in the genomic era.

From the Bosporus to Kopet Dagh: Morphological, Genetic and Bioacoustic Variation in the Chiffchaff in Turkey, the Caucasus and Western Turkmenistan

Abstract
The Chiffchaff superspecies complex occupies almost the entire Palearctic and includes many taxa of different ranks. It is traditionally considered to be one of the most complex problems in the taxonomy of Palearctic birds. We present new data on the genetics, morphology and bioacoustics of the Chiffchaff taxa found in Turkey, the Caucasus, Transcaucasia and Kopet Dagh: ‘greenish' brevirostris, caucasicus, menzbieri and ‘brownish' lorenzii. In southern Turkey, two Chiffchaffs were identified which carried a novel haplotype, recently discovered in Northern Israel. Both individuals from Turkey looked somewhat brighter and more yellowish than typical brevirostris, but their song clearly corresponded to the brevirostris dialect. The form brevirostris, inhabiting the western and central regions of Northern Turkey, was found to be the most distinct among all ‘greenish’ taxa, due to its small body size, wing formula and distinct vocal dialect. Paradoxically, the mitochondrial DNA of brevirostris is almost identical with caucasicus, whereas, in this respect, menzbieri is different from both. We believe that this paradox can be explained if we suppose that caucasicus originated during the ancient hybridization of brevirostris and menzbieri. The relationships between brevirostris and lorenzii, in the mountainous regions of eastern Turkey, show the mismatch between phenotypic and genotypic traits in some individuals that could also be a result of hybridization.
