Kalophrynus meizon — Bornean Sticky Frog
Some other names for this species:
Borneo Big Sticky Frog
The frogs in this genus are difficult to tell apart, and my understanding is that the classifications are all in flux. But of the currently accepted species, K. meizon seems like a strong match for this individual.
