Physalaemus irroratus Cruz, Nascimento & Feio

Ventral aspect ( Fig. 2 E): 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, with irregular margin. The anterior pair is tapered, directed upward and hidden under the posterior pair. The posterior pair is easily discernible from the anterior. Tongue anlage elliptical with three small and tapered lingual papillae in a transverse row, directed upwards. Buccal pockets horizontally oriented. In the BFA about ten papillae on each side, pointing to the center of the arena, thin and tapered, except for the second papillae, which are chela-shaped. There are few pustulations dispersed on the arena. Ventral velum with small projections. Dorsal aspect ( Fig. 2 F): Buccal roof somewhat triangular. Prenarial arena longer than wide, with presence of some short, conical papillae arranged in semicircle on it. Elliptical choanae, large, oriented 45° from transverse plane. Internarial distance 7% of the roof width. In the postnarial arena, presence of one finger-like papilla on each side, large in the basis and serrated in the superior margin, directed upward. The median ridge is in semicircle, twice wider than long, with small projections along its superior margin. Presence of a pair of large chela-shaped lateral ridge papillae. In the BRA about 30 pustulations dispersed on it, and four long and tapered papillae arranged parallel to each other on each side, all directed to the center of BFA. Dorsal velum with no projections.
