anthocharis thoosa

[Kondla, Norbert FOR:EX]

browsing through the lep soc season summary last nite i noticed
reference to a species Anthocharis thoosa. if memory serves, recent
lists place this taxon as a subspecies of anthocharis sara. can anyone
provide a literature citation that i can hunt down to see the rationale
for elevating to species status? thx
