Help with Tropical Moth Identification!!!

Hi All,

I have been sent a image from my friend and I am struggling to identify the species. Even if you cannot name the species then just the Genus would be fantastic or point me in the right direction. I am lost and need some help!

Sorry for the low quality, but this is all I have. The Moth is from Central Sulawesi and I believe it to belong to the family of Geometridae, but I could be wrong? I am no expert in this family. The moth I have been told had a wingspan of about 40-50mm and you can see the shadow of the hand behind the leaf so I believe this to be correct.

If you can offer any help then I would really appreciate it!

Many thanks

Gary
