Physalaemus maximus Feio, Pombal & Caramaschi

Ventral aspect ( Fig. 3 A): At Stage 36, buccal floor somewhat triangular. Presence of one short and tapered infralabial papilla on each side, directed upward. Tongue anlage elliptical with four tapered lingual papillae in a transverse row. Buccal pockets horizontally oriented. In the BFA about 20 pustulations and five to seven long, tapered papillae on each side, some pointing to the center and some directed upward, except for the first on each side that may be larger and bifid. Ventral velum with no projections. Dorsal aspect ( Fig. 3 B): Buccal roof somewhat triangular. Prenarial arena longer than wide, with about some short, conical papillae on it. Elliptical choanae, large, oriented 45° from transverse plane. Internarial distance 8% of the roof width. In the postnarial arena, presence of two large papillae on each side. The posterior pair is larger and has irregular margins and apices; the anterior pair is large in the basis, becoming tapered. The posterior pair is much discernible from the anterior. The median ridge is trapezoid, twice wider than long, with some projections along its margin. Presence of a large and bifid lateral ridge papilla on each side. In the BRA about 40 pustulations dispersed and four–five finger-like papillae on each side directed to the center of BFA. The last papilla on each side may be bifid. Dorsal velum with no projections.
