Physalaemus cicada Bokermann

Ventral aspect ( Fig. 2 A): At Stage 36, buccal floor triangular. Presence of two pairs of infralabial papillae. The posterior pair is large in the basis, tapered in the apex, and with irregular margins, while the anterior pair (hidden under the posterior pair) is small, thin and tapered, and is directed upward. The posterior pair is easily discernible from the anterior. Tongue anlage elliptical with four small and tapered lingual papillae in a transverse row, directed upward. Buccal pockets horizontally oriented. In the BFA presence of four–five finger-like papillae on each side, pointing to the center of the arena and about 20 pustulations dispersed on it. Ventral velum round shaped with small projections. Dorsal aspect ( Fig. 2 B): Buccal roof triangular. Prenarial arena longer than wide. Some short, conical papillae are distributed in a transverse row in the prenarial arena. Elliptical choanae, large, oriented 45° from transverse plane. Internarial distance 7% of the roof width. In the postnarial arena, presence of one large finger-like papilla on each side. The median ridge is trapezoid, about three times wider than long, with irregular superior margin. Presence of a pair of lateral ridge papillae, large and chela-shaped. In the BRA about 40 pustulations dispersed on the arena, limited by three to five finger-like papillae on each side, directed to the center of the arena. Dorsal velum with projections.
