A tadpole in Stage 28 has a body length of 15.6 mm and a total length of 37.5 mm. The body is ovoid, slightly wider than high. The snout is bluntly rounded, nearly truncate, in dorsa view and rounded in profile. The moderately small eyes are situated and directed dorsolaterally and not visible from below. The spiracle is sinistral with its short tube attached to the body wall; the spiracular opening is directed posterodorsally well below the midline at about midlength of the body. The cloacal tube is short, dextral, and attached to the ventral fin. The caudal musculature gradually diminishes in height from the body to an acutely rounded terminus. The dorsal fin originates on the anterior margin of the caudal musculature, is highest at about two-thirds of its length, and gradually diminishes to a bluntly rounded tip. The ventral fin originates on the body wall and is highest at about three-fourths of its length. The oral disc is directed anteroventrally. The median two-thirds of the anterior labium is bare; the rest of the labium bears short, blunt marginal papillae in two rows in the lateral folds and in one row elsewhere. The jaw sheaths are moderately robust and serrated; the anterior sheath is in the form of a broad arch, and the posterior sheath is widely V-shaped. The labial tooth row formula is 2(1)/3; all rows are about equal in length. The body and tail are dark gray.
