Cercotrichas galactotes taxonomy (1 Viewer)

Anyone aware of any genetic or other studies on Rufous-tailed Scrub Robin (Rufous Bush Chat) pointing to or away from any potential split?

Clement/eBird taxonomy in 2019 stated:
page 459, African Scrub-Robin Cercotrichas minor

African Scrub-Robin Cercotrichas minor is lumped with Rufous-tailed Scrub-Robin Cercotrichas galactotes (Keith et al. 1992). Each former species now is recognized as a separate polytypic group: Rufous-tailed Scrub-Robin (Rufous-tailed) Cercotrichas galactotes [galactotes Group], containing the subspecies galactotes, syriaca, and familiaris; and Rufous-tailed Scrub-Robin (African) Cercotrichas galactotes minor/hamertoni, containing the subspecies minor and hamertoni.

Cercotrichas galactotes was collected by Natterer in Gibralter and Algeciras Spain but very close to Africa.

There are two genetic groups in the BOLD barcoding data.

• http://www.boldsystems.org/index.php/Public_BarcodeCluster?clusteruri=BOLD:AAE9627 -- this includes 5 birds from Israel, 2 from Kuwait and 8 from Afghanistan.
• http://www.boldsystems.org/index.php/Public_BarcodeCluster?clusteruri=BOLD:ADG8723 -- this includes 1 (April) bird from Israel and 4 (winter) birds from Djibouti.

There are some pics of the Israeli birds -- the one that clusters with the Djibouti birds is quite deep rufous, the others are distinctly greyer. I assume the first group could be syriaca + familiaris, the other galactotes + minor ? The genetic distance between these two groups is 1.61%.
