Adenomera andreae

External morphology. Description based on one tadpole at Stage 39 (INPA-H 1590). Total length 13.1 mm. Body elongate oval in dorsal view and globular/depressed in lateral view ( Fig. 52A, B ). Snout truncate in dorsal and lateral views. Eyes small, positioned and directed laterally. Nostrils small, circular, laterally positioned near to snout, with opening anterolaterally directed, without a projection on the marginal rim. Oral disc ( Fig. 52C ) anteroventral, non-emarginate; marginal papillae elongate, uniseriate, with a wide a dorsal gap and a narrow ventral gap. Submarginal papillae absent. LTRF 0/0, dermal ridges present. Jaw sheaths narrow, finely serrated; anterior jaw sheath arch-shaped, posterior jaw sheath U-shaped. Spiracle absent. Vent tube medial, fused to the ventral fin, with a medial opening. Caudal musculature of moderate width; in lateral view gradually tapering to a pointed tip. Dorsal fin of moderate height, originating at the tail-body junction, convex; ventral fin of moderate height and convex. Tail tip pointed.

Colour. In preservative dorsum brown, venter cream, tail whitish and fins translucent whitish ( Menin & Rodrigues 2013). In life dorsum brown; venter translucent yellow; fins translucent; tail whitish ( Menin & Rodrigues 2013).

Metamorphs. Dorsum brown with numerous dark marks in most individuals; dorsum brown with two light dorsolateral stripes; venter whitish ( Lima et al. 2012).

Natural history. Eggs are deposited in a foam nest in underground chambers constructed by the males ( Lima et al. 2012) or inside a decomposing fallen log ( Menin & Rodrigues 2013) in terra-firme forests. An egg clutch contained 7 unpigmented eggs ( Menin & Rodrigues 2013). Endotrophic tadpoles complete development in the nest ( Lima et al. 2012).

Comments. Tadpoles of A. andreae from Central Amazonia were illustrated by Hero (1990) and described by Menin & Rodrigues (2013). No morphological variation was observed between tadpoles herein characterized and those drawed in Hero (1990). Tadpoles described by Menin & Rodrigues (2013) differ from those herein characterized by presenting posterior jaw sheath horny, broadly-arched.
