Sabah, Malaysia - ID requests

[Gavin Chan]

Hi Dr Seow, would also like to seek your opinion on a couple of butterflies taken on the same trip.

1. Prosotas sp. Am inclined to P. bhutea

2. Chersonesia sp. (1)
Cyrestis sp Sabah 2023 1.jpg

2. Chersonesia sp. (2) This appears to be similar to the one above, but almost twice it's size.

Thanks in advance!

Edited to correct the genus.
