The masked tree frog, now placed in Leptomantis, is found in Indonesia and Malaysian Borneo, so its Sumatran listing should be checked. It is a relatively small frog, with a pointed snout and dilated finger and toe tips, ranging from pale grey-green to brown, with yellow sides marked with black blotches. It is threatened by habitat loss (Wikipedia, general species account).
