Post 3.
The white band seem a bit small for M. gopara.
The female is undoubtedly M. biggsii.
The Mwlitus species are far more difficult than I expected.
In M. biggsii the FW postdiscal spot 6 is shifted out quite distinctly from spot 5, but there are variation & there may be examples where it is in line or almost so.
M. biggsii, image 3 upperside, images 9 & 10 underside.

No upperside. Status uncertain.

I am afraid without a proper upperside shot it seem impossible to confirm if both M. gopara & gaesa still exist.
The female M. gopara with its distinctive 'tail' is still identifiable from the underside, but no such image is found.
