I found this toad at high elevation (~3000m above sea level) on Mount Kinabalu. It is a moderate sized toad (between 30 and 40mm) that was walking across the trail. Going through my field guides, it appears to be Pelophryne misera (at least visually), but it does not fit as it is far larger than P. misera and it does not have webbing on its hands which is a characteristic of Pelophryne. I've gone through the Frogsofborneo.org options, and have not had success there either. Consequently, I have no idea what the species is.
Ansonia fuliginea is a species of toad in the Bufonidae family. It is endemic to Malaysia. Its natural habitats are subtropical or tropical moist montane forests and rivers. It is threatened by habitat loss.
