Photographed at Phang-nga, southern Thailand. I am pretty sure that this must be Zographetus ogygioides or ogygia.
From looking at images on the web the general colouration would appear to indicate ogygioides, but from other images the spot layout suggests ogygia. I have no images of my own for comparison. I am having a hard time deciding.
I only have the one image.

Both species would be in range.
Help please. With thanks.

It is almost impossible to separate them in the field.

The key the male of ogygia have streaks of specialised scales on some of the lower veins while the male of ogygiodes lacks them.
The difference between the females of the two is also uncertain.

In Singapore there is only Z. ogygia.
The underside is a more uniform red-brown or golden brown.
Male & female.

Compare Z. doxus male & female.

It is probably Z. ogygia.
