Physalaemus camacan Pimenta, Cruz & Silvano

Ventral aspect (Fig. 1 E): At Stage 37, buccal floor slightly triangular. Presence of two pairs of infralabial papillae. The posterior pair is large and has irregular margins and apex, while the anterior pair is short and tapered, with irregular margins. The posterior pair is easily discernible from the anterior pair and it hides the anterior pair. Tongue anlage oval with four long, conical lingual papillae in a transverse row, with smooth surfaces. Small buccal pockets horizontally oriented. In the BFA, presence of five–six papillae on each side; the second papillae are bifid and the others are finger-like papillae, all point to the center of the arena, except for the last papillae that are directed upward. There are few pustulations dispersed on the arena. Ventral velum round with some projections in the margin. Dorsal aspect (Fig. 1 F): Buccal roof slightly triangular. Prenarial arena wider than longer, without papillae or pustulations on it. Choanae elliptical, oriented 45° from transverse plane. Internarial distance 5% the buccal roof length. In the postnarial arena, presence of a pair of tapered papillae, irregular and large in the basis, directed to the center. One chela-shaped lateral ridge papilla at each side. The median ridge is in semicircle, longer than wide, with some irregularities in the margin. The BRA has about 15 pustulations dispersed, limited by four thin and tapered papillae on each side, directed to the center of the arena. Dorsal velum with irregular margin.
