Photo #21267: Pieris dulcinea

Yury, want to share some interesting find concerning differences between Pieris melete and Pieris dulcinea. The publication "Diurnal Lepidoptera of Priargunsky district" by Novosibirsk entomologists V. V. Dubatolov and O. E. Kosterin reads that Pieris dulcinea's back black spot on its forewing is as well emphasized as the front one, whilst Pieris melete has that back black spot quite more emphasized. That was the description of Pieris melete orientis. Can't comment as I am not a pro, just wanted to share.
Also there was that "optimistic" remark: "The systematics of the mountain butterflies of the genus Pieris relative to P. napi (Linnaeus, 1758) remains one of the hardest and unsolved problems in studying the palaearctic Papilionoidea"...

Yury, the answer was the second part of my comment "variability..." and "I have see no any other variants". I'm open to corrections after all.

"Yury, what would you think identifying species in nature photo?"
Vasily, you didn't answer the question.

Yury, what would you think identifying species in nature photo? Species variability matters too, I have see no any other variants though dug through plenty of the Far Eastern Pieris.

Vasily! May I ask something please? What did you base upon to ID this as dulcinea (I checked the link given)? What made you think this a sure thing? Taking into account I'm not a pro, just want to clear things up.

Pieris dulcinea indeed: http://www.euroleps.ch/seiten/s_art.php?art=pier_dulcinea.

Actually, it looks like Pieris dulcinea (Butler, 1882).
Range matches too: "NE. China, the Amur and Ussuri regions to Korea and Japan". Anybody please comment?
