Synapturanus mirandaribeiroi View in CoL View at ENA

External morphology. Description based on six tadpoles at Stage 42 (INPA-H 15838). Total length 15.6 ± 0.5 mm (N = 6). Body ovoid in dorsal view and globular in lateral view ( Fig. 67A, B View FIGURE 67 ). Snout truncated in dorsal view and rounded in lateral view. Eyes positioned and directed laterally. Nostrils unperforated but externally visible as rounded whitish spots positioned dorsolaterally. Mouth terminal, as a simple slit. Jaw sheaths, papillae, and tooth rows absent. Spiracle absent. Vent tube absent. Caudal musculature of moderate width; in lateral view gradually tapering to a pointed tip. Dorsal fin shallow, originating at the tail-body junction, slightly convex; ventral fin shallow, slightly convex. Tail tip rounded.

Colour. In preservative dorsum greyish and venter cream; chromatophores distributed on the head, dorsal region of the body and on dorsal surfaces of the hind limbs and forelimbs ( Menin et al. 2007). In life head and dorsum reddish-brown becoming brighter laterally, with a mottled brown pattern on the flanks and limbs; venter white to cream; tail fins transparent; caudal musculature light brown ( Menin et al. 2007).

Metamorphs. With brown dorsum, flanks comparatively brighter and a mottled brown pattern on the flanks and limbs ( Menin et al. 2007).

Natural history. Clutches contain from 5 to 9 creamy eggs ( Menin et al. 2007). Eggs are deposited in burrows about 5-10 cm below the soil surface in terra-firme forests; development is endotrophic and tadpoles hatch at Stage 42 ( Menin et al. 2007).

Comments. Tadpoles of S. mirandaribeiroi from Central Amazonia were illustrated as S. mirandaribeiroi / S. salseri by Hero (1990) and described by Menin et al. (2007). Tadpoles illustrated by Hero (1990) differ from those herein characterized by presenting a pointed tail tip. No morphological variation was detected between tadpoles herein characterized and those described by Menin et al. (2007).

PHYLLOMEDUSIDAE . Tadpoles of the phyllomedusid species occurring in Central Amazonia belong to two genera with free-swimming tadpoles. The morphology of these tadpoles is very similar.

Genus Callimedusa . Only one species of Callimedusa is found in Central Amazon.
