Hitherto treated as conspecific with D. urbicum, but differs in its much broader white rump patch owing to white uppertail-coverts (2); much shallower tail fork, 1 cm vs 1.5–2 cm depth#R (at least 2); and parapatric distribution in Buryatia#R (3), with no evidence of interbreeding elsewhere in contact zone (published statements of intergradation at R Yenisey#R#R based on misreading of the original#R). Monotypic.
E Asia from middle and upper R Yenisey, Altai Mts and Mongolia E to Anadyrland, Sea of Okhotsk and NE China; probably winters mainly SE Asia.
