Limnophys cerastes is a large member of the genus, ranging from 46-55.8 mm SVL. Snout is truncate or weakly sloping when viewed laterally. Frontoparietals possess low lateral crests that do not form bosses in the interorbital region nor do they extend onto nasals. Tympanum is 33-50% eye length in females while 50-60% in males. Ulnar tubercles are present and are not enlarged. Two palmar tubercles are present, of which the outer is larger and bifid. Fingers lack fringes. The thumb is longer than the second digit of the hand. The upper eyelid possesses an elongate tubercle on the posterolateral corner of the eyelid. Toes have pads and are broader than long; much larger than the pads found on the fingers. Head is broader than the body (head width is 45.8% SVL). Upper eyelid is broad and has a width of 140.6% inter-orbital distance. The hind limbs are long and when the limbs are adpressed the heel may reach between the eye and tip of snout. In preservative, the coloration is as follows: dorsum is brown and the ridges and tubercles are dark brown to black. Limbs are barred with dark brown and the dark bars are narrower than the brown interspaces. The venter and undersides of the limbs are cream with moderate to intense brown mottling and reticulation. Throat is brown punctuated with cream.
