In some individuals, these markings consist of several large, darker, irregular blotches and semicircular spots with black borders, while in others, they are limited to the posterior portions of the head or the interorbital region.
In most individuals, the venter is uniform dark gray with minute white spots on the warts.
Males seem to tolerate exposure and call from perches such as stumps and rocks, or on open forest floor or leaf litter.
[1][2] The species is common along clear mountain streams and rivers, and seems to tolerate a degree of habitat disturbance.
Nevertheless, habitat loss caused by shifting, slash-and-burn agriculture and small-scale wood collection is threatening this species.
