Description
The body of this species is large and stocky. The canthus is blunt and the tympanum is hidden under the skin. There are 3-5 vomerine teeth. The webbing is very well developed and the tips of the toes and fingers are small discs. The skin of the back has scattered tubercles that have white asperities. The dorsolateral fold is only evident anteriorly, but the supratympanic fold is very prominent. There is also a fang-like projection coming from the tip of the lower jaw; it is larger in the males. There are a pair of vocal sacs and openings on the inner side of the mouth. The nuptial pads in males are not well developed and have semitransparent white asperities. The mean snout to vent length for males is 99 mm (range 79-117), and for females it is 85 mm (range 72-91).

Because this species has only 22 chromosomes, there is common ancestry with the Taiwanese population of R. kuhlii.
