well, I'll follow back :)

Well I believe I'd go by spots and shape over color. Conchyloctenia tigrina is an African species. Is there a record for Indonesia like for Aspidomorpha deusta? I don't know...
The Leopard has 3 spots on the "pronutum" (the first plate covering/behind the head) http://www.biol.uni.wroc.pl/cassidae/kat... and yours has 2 spots like Aspidomorpha deusta. The leopard's spots along the margin are very numerous in all examples but on yours there are a couple of large fused patches... The corners of the elytra behind the head on yours are sharp, but on the leopard they are rounded... Anyway, just some things to compare :-)

I think it's more like a Leopard Tortoise Beetle, because essentially translucent yellowish color.
Thank you for your kind help @Phillip & @Frazier. :)

I'm sorry I couldn't tell you a better reference, but this is a rare species and people don't usually document them, hope I helped though!
Great captures!
