A tadpole in Stage 25 has a body length of 12.5 mm and a total length of 30.0. The body is globular and wider than high. The snout is bluntly rounded in dorsal view and rounded in profile. The small eyes are situated dorsally, directed dorsolaterally, and not visible from below. The spiracle is sinistral with a short tube attached to body throughout its length; the spiracular opening is directed nearly posteriorly just below the midline at about midlength of the body. The cloacal tube is short, cone-shaped, dextral, and attached to the ventral fin. The caudal musculature is robust, about equal in height throughout the proximal two-fifths of the tail, and gradually diminishes to a pointed tip. The dorsal fin originates on the proximal part of the caudal musculature, reaches its greatest height at about two-thirds the length of the tail, and declines to an acutely rounded tip; ventral fin originates on the body and is highest at the midlength of the tail. The oral disc is directed anteroventrally. The median half of the anterior labium is bare; elsewhere the labia bear a single row of small, subconical marginal papillae. The jaw sheaths are narrow and finely serrate; the anterior sheath forms a broad arch, and the posterior sheath is broadly V-shaped. The labial tooth row formula is 2(1)/3; A2 is the longest, and P1 is the shortest. The body is brown, and the tail is pale orange.
