A recently metamorphosed young has a snout-vent length of 15 mm.; the
head is as long as wide, the eyes are prominent; the limbs are weakly
barred; the skin is rugose above and granular below. The venter is
immaculate; the dorsum and limbs are gray-brown in preservative (pale
green in life). The interorbital space, supratympanic fold, and
scapular region are darker than the rest of the body; the fingers lack
webbing; the webbing on the foot is the same as in adults; small
metatarsal tubercles are present, but the tarsal fold is absent.
