Billis buto cowani ?

[Glorious Begum]

Need help to confirm the ID. Is this Billis buto cowani ?

Shot in Malaysia

I think it's Britomartis cleoboides viga from the eye colour and the size of the black tornal spots. In Bullis buto the upper black spot is much larger than the one at the anal angle. Nice shot

Thanks Aaron.

It looks like B. cleoboides viga.

Wow what a classic shot! The differences between these royals are so subtle... I'm always surprised you guys can differentiate them so well.
