Abstract

Proceratophrys dibernardoi is a newly described species belonging to the Proceratophrys cristiceps group. Herein, we describe the external morphology of tadpoles of P. dibernardoi. Although external larval morphology of P. cristiceps group members is quite similar, the tadpole of P. dibernardoi may be distinguished by a combination of morphological traits, such as body shape that is elliptical in dorsal view and depressed in lateral view; a snout that is rounded in dorsal and lateral views; small, reniform nares with a small marginal rim; and a spiracle with its centripetal wall completely fused to the body wall. The oral disc is ventrally located, with lateroventral emarginations; its tooth row formula is 2(2)/3(1).

Resumo

Proceratophrys dibernardoi é uma espécie recém-descrita pertencente ao grupo Proceratophrys cristiceps. Aqui, nós descrevemos a morfologia externa dos girinos de P. dibernardoi. Apesar da morfologia externa das larvas de anuros de espécies incluídas no grupo P. cristiceps ser bastante semelhante, o girino de P. dibernardoi pode ser distinguido pela combinação de características morfológicas como formato do corpo elíptico em vista dorsal e deprimido em vista lateral; focinho arredondado em vista lateral e dorsal, narinas pequenas e reniformes, com pequena projeção marginal, e espiráculo com parede interna totalmente fundida ao corpo. O disco oral é localizado ventralmente, com emarginações lateroventrais e fórmula dentária 2(2)/3(1).
