Physalaemus soaresi Izeckson

Ventral aspect (Fig. 4A): At Stage 33, buccal floor triangular. Presence of two pairs of infralabial papilla. The posterior pair is a large finger-like papillae; the anterior pair is short and tapered, directed upward. Tongue anlage oval with three long and tapered lingual papillae in a transverse row, directed upwards. Buccal pockets horizontally oriented. In the BFA there are few pustulation dispersed and about two–three papillae on each side, parallel to each other. The sencond papillae are chela-shaped and the others are finger-like and long. Ventral velum with small projections. Dorsal aspect (Fig. 4B): Buccal roof somewhat triangular. Prenarial arena longer than wide, with three short, flattened papillae on the midline. Elliptical choanae, large, oriented 45° from transverse plane. Internarial distance 6% of the roof width. In the postnarial arena, presence of one long finger-like papilla on each side, directed upward. The median ridge is trapezoid, four times wider than long, with some projections in the superior margin. Presence of a pair of lateral ridge papillae, large and bifid in the basis with irregular margins. In the BRA there are few pustulations dispersed and four long and tapered papillae on each side arranged parallel to each other and directed to the center of BFA. Dorsal velum with no projections.
