The double medial line seen faintly on the right forewing, seems to me to be the wrong shape for Poecilasthena

The shape of the forewing apex doesn't match either of these species, and I think the contrast in forewing and hindwing background colours of Euloxia meandaria would be noticeable even in a worn specimen. We need to look further in the Geometrinae.

I think I was wrong about the forewing shape not suiting P. thalassias
