Photographed in Yala. I would narrow this down to either M.chinesis or M. biggsii. What would be the best differentiation please?

Miletus biggsii male.

The two are practically identical on the underside.
However, M. biggsii have the FW postdiscal band's spot 6 dislocated & shifted out.
Male & female Singapore.

Many thanks. I had noticed those spots out of alignment and wondered if that was a good feature.
