Two Nacaduba species photographed at Doi Inthanon. I think the first image is N. beroe because:
- the dark edges inside the discal bands are not very strong.
- the hindwing spot is not particularly large.
- the white edges to the marginal spots are not very pointed.

I think Image 2 is N. berenice as:
- the white edges to the marginal spots are very pointed.
- the hindwing spot is faily large.

Would these be correct please?
Many thanks
