No obvious markings except faint dark spot on each forewing. Forewing costa same colour as wings rules out many Geometrinae genera. Hindwings wrong shape for Traminda.

I think this looks very much like P. thalassias ( see the other CNM postings). There is a faint spot visible on the LHS forewing in the right postion. - and very faintky on the RHS too. I think the hindwing shape is right for P. thalassis, assuming the other IDs are correct.
