Abstract

We have analyzed morphological characters in tadpoles of fourteen anuran species. The species considered are Bufo arenaum, B. paracnemis, Leptodactylus chaquensis, L. latinasus, Odontopbynus americanus, O. lavillai, Phrynohyas venulosa, Phyllomedusa sauvagii, Physalaemus biligonigerus, P. cuqui, Pleurodema borellii, P. tucumana, Scinax fuscovaria and S. nasica. They develop in similar temporary ponds of Northwestern of Argentina. We characterized the larvae of each species by the analyses on external morphology, internal oral features, chondrocranium and visceral archs. Some of these morphological aspects have been discussed with proposal hypotheses about generalized tadpoles.
