Physalaemus rupestris Caramaschi, Carcerelli & Feio

Ventral aspect ( Fig. 3 C): At Stage 36, buccal floor triangular. Presence of one pair of infralabial papillae, large in the basis and tapered, directed upward. Tongue anlage elliptical with four long and tapered lingual papillae in a transverse row, directed upwards; the papillae found in the extremities are smaller and flattened. Buccal pockets horizontally oriented. Presence of few pustulations dispersed on the BFA. There are four long, finger-like papillae on each side, pointing to the center of the arena, and about ten papillae closer to the velum, directed upwards. Ventral velum with small projections. Dorsal aspect ( Fig. 3 D): Buccal roof somewhat triangular. Prenarial arena longer than wide, with two short, flattened papillae. Elliptical choanae, large, oriented 45° from transverse plane. Internarial distance 9% of the roof width. In the postnarial arena, presence of two papillae on each side. The posterior pair is a large finger-like papilla with irregular margin that points to the center and the anterior pair is a smaller and tapered. The posterior pair is discernible from the anterior. There is one lateral ridge papilla on each side, large in the basis and chela-shaped. The median ridge is triangular, about two times wider than long. In the BRA 30 pustulations in the arena and about six finger-like papillae on each side, arranged parallel to each other and directed to the center of BRA. Dorsal velum with no projections.
