[1][3][4][5] It is endemic to Borneo and is found in Brunei, south-central Sarawak (Malaysia), and Kalimantan (Indonesia).

An elongate gland is located above and behind the ear, dissolving into a series of warts that separate the dorsum from the flanks.

[5] When disturbed, these frogs secrete a sticky, white substance from their skin.

[5] Kalophrynus intermedius lives in leaf-litter on the floor of closed-canopy forests at elevations of 150–300 m (490–980 ft) above sea level.

It does not tolerate habitat disturbance and is therefore threatened by clear-cutting of lowland tropical rainforests for logging and palm oil plantations.
