What are their recommendations concerning taxonomy?
Click to expand...
They're generally not extremely affirmative.

Masked owls:
a single species-level taxon:
Australian Masked Owl T. novaehollandiae (Stephens, 1826)
Including subspecies calabyi, castanops, cayelii, manusi, novaehollandiae, sororcula (tentatively including the Australian populations of subspecies galei, kimberli and melvillensis not sampled yet in genetic studies).

Sooty owls:
suggesting that T. multipunctata is more likely a subspecies of T. tenebricosa

Grass owls:
more genetic data are required before we can draw any firm conclusion regarding the degree of their phylogenetic divergence.

American barn owls:
For the time being, a species-level split of T. furcata from T. alba and T. javanica as previously advocated by some authors (Aliabadian et al., 2016; Gill and Donsker, 2018) seems justified, keeping in mind that phylogenetic relationships of T. f. punctatissima and T. glaucops are still unclear. Genetic information on the dark island forms from Puerto Rico (T. glaucops cavatica) and from the Lesser Antilles (T. g. nigrescens, T. g. insularis) missing to date are needed for a concise species-level classification of the American Barn Owl, T. furcata (sensu Gill and Donsker, 2018) and the Ashy-faced Owl, T. glaucops.

Western barn owls:
Common Barn Owls from Africa and Europe seem to be undifferentiated from each other, except the insular population of São Tomé Island, T. alba thomensis. This population [...] potentially deserving consideration of species-status.

Eastern barn owls:
a single species-level taxon ( Figure 2):
Eastern Barn Owl – Tyto javanica (J. F. Gmelin, 1788)
Including subspecies delicatula, interposita, javanica, lifuensis, lulu, nigrobrunnea, rosenbergii, stertens and sumbaensis (tentatively including crassirostris, meeki and pelengensis, not sampled yet in genetic studies)

Of Congo Bay Owl, from Lynx HBW 5: 75

Occasionally treated as a race of P. badius, but this seems hardly probable, and the two do not appear closely related. Inclusion in Phodilus perhaps questionable; present species shows some similarities to P. badius in plumage coloration, but shape of facial disc rather different, more heart-shaped as in Tyto.

Still in Phodilus in IOC; any change in this paper?
 
Eastern Barn Owl seems to show clearer structure than Western or American, I wouldn't be surprised if this was further split by some lists across Wallace's line as discussed in the text, rather than the conservative lump proposed:

A reasonable re-arrangement of this group would result in two sister species pairs: I) T. rosenbergi and T. delicatula (sensu Dickinson and Remsen Jr, 2013); and II) T. nigrobrunnea and T. javanica, with the latter taxon restricted to the continental Southeast Asian and insular Indomalayan populations north of Wallace’s line. However, genetic distances between the two insular endemics and each of the two T. javanica clades are as low as 0.4–0.5 %, and sister-group relationships were only poorly supported. Therefore, although we are apprehensive due to the decrease in species diversity this would cause, a more conservative approach considering the very shallow within-clade divergences, like in the case of the Tasmanian Masked Owl T. novaehollandiae, would result in a single species-level taxon

Any idea what's happened to Andaman form, deroepstorffi?

Do Vera et al mention it?
Click to expand...
They mention it, but did not sample it -
The phylogenetic affinities and the taxonomic status of the so far unstudied Andaman Islands endemic being treated as a full species Tyto deroepstorffi by some authors (Clements et al., 2016; Dickinson and Remsen Jr, 2013; Gill and Donsker, 2018) remains an open question for future research.

(It should be "Uva et al.", I believe - Vera being her first name.)

Thank you - and apologies to Vera! - though they've got it wrong at MP&E too:

"Please cite this article as: Vera, U., Martin, P., Alice, C., Luca, F., Alexandre, R., Comprehensive molecular
phylogeny of barn owls and relatives (Family: Tytonidae), and their six major Pleistocene radiations, Molecular
Phylogenetics and Evolution (2018), doi: https://doi.org/10.1016/j.ympev.2018.03.013"

Barn Owls: The Barn Owls have been rearranged based on Uva et al. (2018). Their results suggest that some adjustment to species limits will be needed, but it is not yet clear to me how best to do that.

They've got ALL of the names wrong in that citation: ScienceDirect gives their names as "Uva Vera, Päckert Martin, Cibois Alice, Fumagalli Luca, Roulin Alexandre".
