Notes

Bozano et al.,2016 assumed that the nominotypical subspecies described by Doubleday,1842 is the same taxon as in China. However, here I treat it as the Indian population as in the past. Further taxonomic study is needed.
There are several specimens labeled 'Siam' in the NHML, but no detailed data is available and it is considered to be an erroneous locality.
