Clearly A Winthemiini, quite likely Winthemia. Difficult genus in the Far Easr. Need to check the literature. Sphingidae are well-known hosts for this genus.

This is a specimen escaped from the same host. I considered this specimen and the uploaded specimen are different species because the presence of yellow powdery. Are these specimens the same species?
I identified this species is probably
Winthemia sp. near
cruentata.

Did you use Shima’s key for Far East ?

I couldn't find Shima's paper. I used the genus key from MOSCHWEB and Tschorsnig & Herting's key for Central Europe.
In Korea, there are 2
Winthemia species are recorded:
W. cruentata and
W. venusta.

OK. There are many more species in east Asia.
You really can’t use Tschorsnig & Herting in Korea !
I will look in to it.

OK. Could you please make a picture of the ventral side of the abdomen and/or check if there is a pair of patches of specialized fluffy hairs on 4th (apparent: 3th) tergite ?
And could you change the title of this thread in 'Winthemia', please ?

So, there are clear flurs of fluffy hairs on both tergites 4 and 5. This rules cruentata out.
The sexual dimorphism is striking.
It does not fit any of the Japanese species as described by Shima.
