Marbled tree toad (Rentapia everetti) suspected. Sarawak, Borneo.

I found this beautiful toad in the mountains about an hour south of Kuching. If my ID is correct he is mostly arboreal and I was lucky to find him. The organization "Frogs of Borneo" says that the tadpoles for this species are "unknown". I suspect this indicates how little study has taken place in this extraordinarily diverse area. I'd appreciate any confirmation or disagreement on this ID.
