Is this Caltoris cormasa? The first butterfly that most of us shot.

No. This is Caltoris bromus. I believed it is the same presented by Sunny in the other thread.
The upper cellspot is just visible above the hindwing margin.

C. cormasa have a deeper rusty red brown underside and the antennal shaft on the upper & outer sides is actually brown.

Lighting conditions & camera settings can cause a lot of confusion as the colouration becomes different.

In C. bromus the forewing & hindwing are the same colour.
In C. cormasa the hindwing is a deeper/darker colour than the forewing.
