Nadia, what makes you think this is Problepsis conjunctiva rather than Problepsis eucircota?
I suspect it is the latter
The main difference is as follows:
P. eucircota f/w with a small yellow medial orbicular mark above the dorsum is discrete, lightly ringed with metallic scales; does not fuse with the large orbicular stigma
P. conjunctiva f/w with a diffuse greyish-yellow smudge beneathand contiguous with the large orbicular stigma.
