Description

Colour. In preservative, body light brown to brown, venter paler, belly translucent; caudal musculature light brown, tail fins translucent; caudal musculature and fins covered with melanophores forming many irregular brown blotches. In life, dorsum grayish brown, lateral of the body mottled, venter translucent; caudal musculature pale brown, tail fins translucent, both with melanophores forming irregular blotches (Fig. 5 D). Variation. LTRF ranges between 2 (2) / 3 (less frequent) and 2 (2) / 3 (1) (more frequent) after Stage 27. Metamorphs. Similar to adults. Body brown with two distinct, dark dorsolateral stripes starting in the snout, passing through eyes and continuing towards end of body; limbs brown; venter creamy-colored (Fig. 5 E). Natural history. Eggs are deposited in the forest floor in rolled or doubled fallen leaves. Clutches contain from 6 to 14 eggs (Juncá 1998; Lima et al. 2012). Tadpoles are carried on the back of the males to small, temporary, isolated or streamside ponds and puddles in terra-firme forests and forest edge (Juncá 1998; Lima et al. 2012; this study). Larvae are found in all months of the year. Ability to colonize very small water bodies is indicated by the observation of tadpoles of A. sumtuosus on fallen palm leaves or bucket lids filled with rainwater only a few millimeters deep (this study). Larvae are benthic and camouflaged against the substrate. Tadpoles of A. sumtuosus are prey to tadpoles of Leptodactylus rhodomystax (Rodrigues et al. 2007) and to Pipa arrabali (Buchacher 1993). In experiments larvae were found to consume few anuran eggs and to be preyed upon by dragonfly larvae and fish (Hero 1991; Magnusson & Hero 1991).
