Tadpole description: overall body is elliptical with a maximum length of 44.7 mm (Pezzuti et al. 2021). The tadpole snout is oval shaped, with small to medium-sized round nostrils, located dorsally, directed antero-laterally; the nostril distance to snout 32–41% of eye–snout distance; the nostril lacks any fleshy projection on the medial margin. Its round distinct eyes are located dorsally. Medium-sized oral disc is emarginated ventrally and latero-ventrally; a single row of alternate marginal papillae anteriorly and posteriorly, with biserial lateral portions with wide anterior gap; two to five submarginal papillae scattered laterally in oral disc. Small flaps with labial teeth present laterally and anteriorly in oral disc. The jaw sheaths are narrow and finely serrated on margins with an arc-shaped upper jaw sheath and V-shaped lower jaw sheath; both lower and upper sheaths are same width. Sinistral spiracle. The robust tail has an intermediate height with a round tip and intermediate fins both dorsal and ventral but dorsal fin may be higher than ventral (Pezzuti et al. 2021).
Tadpole coloration in life is overall black including its body, tail, fins and spiracle; the latter may have white spots along the ventral line to the base of the vent. The eyes are black and speckled with silver as is the pupil ring (Pezzuti et al. 2021).
