Resumo
We describe the external morphology of the tadpole of Proceratophrys izecksohni Dias, Amaro, Carvalho-e-Silva & Rodrigues, 2013, its internal oral features, and chondrocranial anatomy, based on specimens collected at the type locality. The tadpole has short and oval body, spiracle with inner wall fused to the body, and oral formula 2/3(1). The oral cavity of P. izecksohni is typical of stream-dwelling tadpoles, with several papillae and pustulations. The chondrocranium is longer than wide and the suprarostral corpora are free ventromedially. The palatoquadrate has a well developed processus pseudopterygoideus. We also compare the tadpole of P. izecksohni with tadpoles those of other species of the genus, emphasizing the usage of larval morphology to assist in the systematic of the genus.
