Short visit a Thale Ban NP (Satun)

Does that really count to make it merguia? I see it as within the variation of amabilis especially since merguia looks quite different. Here you can clearly see the orange and silvery scales at the tornal area. The black markings above the round black tornal spot and the configuration of the post-discal streak are very different from amabilis.

This at first appears confusing, but I agree with Aaron here.
The forms of both species pertain to the subspecies in Malaya.

In H. merguia the following points may be noted.
1. FW is more heavily orange shaded to the postdiscal band.
2. The marginal spot in space 5 is always partially orange (black in amabilis).
3. The submarginal spot in space 3 is shaped like a broad arrowhead. ( a short bar in amabilis.)
4. The HW postdiscal streaks are broader & separated vs narrower & longer & tend to merge in space 1b in amabilis..
5. As stated in C&P4 the orange vein 2 & the silver scalings in space 1b.

Another example of H. merguia from Malaya.
