Hello Helene,
Peter explained it completely right.
The first ones are nagyi from Cherating and the second form is the one from Kuantan.
This nagyi-form has a larger distribution area than the Cherating-form and lives more south.
Here is a picture how the nagyis from Cherating, which you got from me, will look in breeding colours.
You can see there the light-blue band in the claudal of the male. One cannot find at the Kuantan-nagyis.
Additionally, I added a photo of the location where Bernd and I caught this species.
