Has been placed in a separate genus, Callisitta. Lustrous blue coloration may suggest an affinity with S. frontalis and S. azurea, but E Himalayan centre of distribution and unique plumage pattern militate against this; relationships as yet inadequately resolved via molecular testing#R. Monotypic.

Distribution:

NE India (NE West Bengal, Sikkim, Arunachal Pradesh and Assam), S Bhutan, N, W & E Myanmar (Kachin, Mt Sarameti, Arakan Hills, and Salween–Mekong watershed E of Mong Hang), S China (Huanglianshan Nature Reserve, in S Yunnan), N Thailand (Doi Phu Kha National Park, in Nan Province), N & EC Laos (Annamite Range) and N Vietnam (scattered localities in N Tonkin). Records in NE Bangladesh and Khasi Hills in Meghalaya (NE India) require confirmation#R.
