The dorsum is dark brown and has a few yellowish or white spots. A narrow light yellow inter-orbital bar is present. The limbs have few white to light yellow bars. The throat is white and has a few brown spots. The belly is immaculate whitish, but some individuals have a few brown spots.

Habitat and conservation

''Cycloramphus faustoi'' are known from a small valley in a dry stream bed at elevations of above sea level. The stream is bordered by Atlantic forest. During the rainy season, the water trickles through this valley. Both males and females were spotted in rock crevices; they were wary and went into hiding when disturbed. Reproduction seems to occur in August when, following a rainy afternoon, males were heard calling at night and a females found guarding an egg clutch consisting of 31 eggs; the female did not leave even when disturbed. This species appears to be scarce within its small range. Moreover, its habitat is threatened by fires caused by artillery training activities. Hence, it is listed as " critically endangered" by the
