I don't think the following paper has been picked up by forum members:
Collar, N.J., Boesman, P. (2019). The taxonomy of certain Asio and Bubo owl species in Africa and Arabia. The Bulletin of the African Bird Club 26(2):155 - 169.

Besides documenting the differences with their closest relative for A. abyssinicus, B. ascalaphus and B. cinerascens (all recognized species in most taxonomies, but based on very limited evidence to date) we also documented species-level differences (phenotypic and vocal) for B. milesi. This last taxon hasn't yet been widely recognized as a full species.
Genetic data were not discussed in the paper.

In HBW/BLI taxonomy, I believe B. milesi reaches the required criterium for species status. In IOC taxonomy, I noticed that Sunda Owlet was split from Collared Owlet based on voice and a single morphologic difference (Gwee et al. 2019), so I can hardly imagine the outcome for B. milesi (having stronger morphological distinctiveness and similar vocal separation) would be different if considered…

Athene noctua

Cheng-He Sun, Hong-Yi Liu, Xiao Min, Chang-Hu Lu. Mitogenome of the little owl Athene noctua and phylogenetic analysis of Strigidae. Int. J. Biol. Mac. 151, 924-931. DOI: 10.1016/j.ijbiomac.2020.02.238

Abstract:

New advances in molecular approaches for DNA analysis have enhanced our understanding of the phylogenetic relationship of birds. The Little Owl (Athene noctua) is of great significance for the integrated management of forest diseases and control of regional pests. Here, we sequenced and annotated the 17,772 bp complete mitogenome of A. noctua. The mitogenome encoded 37 typical mitochondrial genes: 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA, and one non-coding control region (D-loop). The organization and location of genes in the A. noctua mitogenome were consistent with those reported for other Strigidae birds. Phylogenetic relationships based on Bayesian inference and Maximum likelihood methods showed that A. noctua has close relationships with Athene brama and Glaucidium cuculoides, confirming that A. noctua belongs to the Strigidae family. The phylogenetic relationships among seven genera of the Strigidae family used in this study were: Ninox and the other six genera were far apart, Otus and the clade ((Bubo + Strix) + Asio) were clustered into one branch, and Athene and Glaucidium were clustered into one branch. This phylogenetic classification is consistent with prior taxonomic studies on the Strigidae family. Our results provide new mitogenomic data to support further phylogenetic and taxonomic studies of Strigidae.

Bubo is biphyletic, with lacteus, shelleyi, sumatranus, nipalensis, philippensis and blakistoni grouped with Ketupa (Fjeldså comm)



IOC would have information that we don't have, or that would not yet published ?
To my knowledge, Bubo philippensis has never been analyzed in phylogenetic studies. I'm curious to know their position within the Bubo/Ketupa group

It has certainly been barcoded. A quick scout on BOLD and Genbank provided a tentative result. It seems to come out in a clade with K. ketupu and K. blakistoni. Depending on the tree drawn it could be sister to either species.

Bubo bubo

Meng Meng, Jianzhang Ma, Muhammad Younis Laghari & Jianwei Ji (2020) Genetic analysis of three wild Eurasian eagle-owl subspecies, B. b. kiautschensis, B. b. ussuriensis, and B. b. tibetanus, in Chinese populations, Mitochondrial DNA Part B, 5:3, 3775-3777, DOI: 10.1080/23802359.2020.1839363

Abstract:

The Eurasian eagle-owl (Bubo bubo) is distributed throughout Asia and Europe and contains approximately twelve subspecies. Three subspecies, B. b. kiautschensis, B. b. ussuriensis, and B. b. tibetanus, are separately distributed in the refugia and plateau habitats of China. However, the genetics of these subspecies and populations have not been studied. Genetic differences were investigated among 32 individuals from six populations of these three B. bubo subspecies based on the mitochondrial genome. Low genetic diversity but high haplotype diversity was observed in these subspecies. The phylogenetic relationship of three B. bubo subspecies distributed in China was proven to be coordinated with geographic and environmental gradients. This study provides the first detailed insights into the mitochondrial genetic diversity of three Eurasian eagle-owl subspecies distributed in China and demonstrates the utility of the mitochondrial genome in intraspecific genetic population analyses of these eagle-owls.

Abstract​

In the article the research’s results of phylogeography, genetic diversity, genetic structure and demographic characteristics of the boreal owl population in Eurasia are given. The first domain of control region of mtDNA is used as a genetic marker. The sample size was 59 specimens. The population of boreal owl is characteristic of high genetic diversity and it has signs of rapid expansion in the past as revealed by analysis of CR1 mtDNA polymorphism. Genetic differentiation between birds from the west and the east part of the species range is shown. The level of found population genetic differentiation isn’t high that can be explained by gene flow in the past and possible at the present time. We didn’t reveal any signs of genetic differentiation for boreal owl population according to subspecies (between A. f. funereus and A. f. pallens) which are distinguished for the studying area.


Enjoy,

Abstract
The typical owl family (Strigidae) comprises 194 species in 28 genera, 14 of which are monotypic. Relationships within and among genera in the typical owls have been challenging to discern because mitochondrial data have produced equivocal results and because many monotypic genera have been omitted from previous molecular analyses. Here, we collected and analyzed DNA sequences of ultraconserved elements (UCEs) from 43 species of typical owls to produce concatenated and multispecies coalescent-based phylogenetic hypotheses for all but one genus in the typical owl family. Our results reveal extensive paraphyly of taxonomic groups across phylogenies inferred using different analytical approaches and suggest the genera Athene, Otus, Asio, Megascops, Bubo, and Strix are paraphyletic, whereas Ninox and Glaucidium are polyphyletic. Secondary analyses of protein-coding mitochondrial genes harvested from off-target sequencing reads and mitochondrial genomes downloaded from GenBank generally support the extent of paraphyly we observe, although some disagreements exist at higher taxonomic levels between our nuclear and mitochondrial phylogenetic hypotheses. Overall, our results demonstrate the importance of taxon sampling for understanding and describing evolutionary relationships in this group, as well as the need for additional sampling, study, and taxonomic revision of typical owl species. Additionally, our findings highlight how both divergence and convergence in morphological characters have obscured our understanding of the evolutionary history of typical owls, particularly those with insular distributions.
