Adult morphology Snout-vent of about 45 mm or more. Males smaller than females. Head small, flattened, without cephaIic crests; a constriction between head and body. Snout short, rounded and tumefact. Interocular distance equal to upper eyelid and subequal to the eye diameter. Nostrils at equal distance between eye and tip of snout. Tympanum concealed. Tongue subcircular, slightly notched behind, its wideness more than half of the opening of the mouth. Parotoids moderate, oval, dorsally located, on a line towards the center of the neck.

The distance eye-base of tail distance eye-snout ratio is 3.3. A specimen in stage 39 has a body length of 10.2 mm and a total length of 16.0 mm. Body ovoid in lateral view, two times longer than deep. Eyes small (interocular distance 2.3 times the eye diameter), directed anterodorsolaterally. Nostrils evident anterodorsally, pigmented, much closer to eyes than to tip of snout. Spiracle sinistral, short, and lying at about mid-point on body, opening posterolaterally. Anal tube median, short. The caudal musculature i s well developed. Caudal fin rounded at its tip, not extending about the body. Mouth small, anteromedial, labial papillae interrupted anteriorly and posteriorly; tooth rows 2/3. Horny beak black and well developed. Color in life; dark-brown, internal organs not visible.
