Species of the Gonocephalus genus occur throughout Sunda (Peninsular Malaysia, Borneo, Java, Sumatra) and also in the southern Philippines. The Borneo Anglehead Agamid is, as its name suggests, limited to Borneo. It mainly inhabits lowland primary rainforest below 700 metres but at Mount Kinabalu can be found at higher elevations.

The dorsal and lateral surfaces are mottled olive green or brownish-green, and the ventral surface is pale. The tail has a series of thick olive-green bands. Its remarkable crest extends from the above the neck along the entire length of the body to the base of the tail.
