Youngsters of Gonocephalus borneensis and Gonocephalus liogaster look very similar, and I only saw youngsters of this species. However, I'm reasonably sure from close examination of the scales on the face that this is G. borneensis, because it doesn't have a semicircle of enlarged scales between the eye and the mouth. See how I spend my time?

My Travelogues and Trip Lists page includes a complete list of the herps I saw in the wild on this trip to Malaysia, as well as a travelogue of the trip.

Another youngster from another wild area near Kuching. Also lacking those tell-tale enlarged scales, making this G. borneensis by default.
