Notes

This taxon is intermediate between ssp.pyramus and the nominotypical subspecies. Some examples from Lao Cai, N.W.Vietnam tend to have closer markings to ssp.pyramus.
The populations in S.Vietnam and S.E.Thailand seem to be slightly different from ssp.shinkaii. Monastyrskii et al.,2011 recorded it from Cambodia and treated it as the nominotypical subspecies. I consider this population to be identical to S.E.Thailand - S.Vietnam ones from a biogeographic point of view. Further taxonomic study is needed.
