Notes

Monastyrskii,2008 treated this taxon as a distinct species. However, the relationship and taxonomic status of louisa group including mathilda, eamesi and devyatkini are still unclear. I tentatively follow the treatment of Monastyriskii.
The population from Nan, N.E.Thailand appears to be this taxon. The populations from Phrae and the eastern side of Lampang, N.Thailand are slightly different, being highly variable and unstable. In general, individuals from Chiang Rai to the western side of Lampang are similar to ssp.siamensis, but the ground color of the upper side is darker and occasionally individuals rather similar to this taxon occur. It seems to be a transition to ssp.siamensis. Further taxonomic and distributional studies, including DNA analysis, are needed.
