I reckon I can just see a white edge to the costa on the right forewing.

Agreed. But can it be separated from I. inversata?

The accepted wisdom is that scales between the bases of the antennae is light in the case of inversata and light in the case of costaria.

I think you may have meant 'darker' in the case of I. inversata. Difficult to see the scales between the bases of the antennae in this case.

Yes, sorry for typo
