Abstract

Description of tadpole: Body ovoid in dorsal view and globular/depressed in lateral view (Figure 1A). Body about 38% ± 1.57 (depending on the stage) of the total length. Snout rounded in dorsal and lateral views. Nostrils rounded, with opening directed dorsally. Eyes dorsal, laterally directed. Spiracle sinistral, medium-sized, narrow, with opening directed
postero-dorsally, located at the middle third of the body; centripetal wall of the spiracle tube fused to the body wall. Vent tube broad, medial, attached to ventral fin, with dextral opening. Tail approximately 16% ± 9.73 higher than body (depending on the stage). Tail long, about 61% ± 1.57 of the total length (depending on the stage). Dorsal fin origin at the body-tail junction. Dorsal fin of moderate size, weakly convex. Ventral fin low, approximately parallel to caudal muscle.
Caudal muscle poorly defined, semi-transparent in life. Fins slightly tapered, with rounded tip
