The genus Eupsophus is characterized by endotrophic larvae that inhabit water-filled cavities. The larvae feed from large yolk reserves during metamorphosis. The external morphology has been described for four of the ten known species and data on larval chondrocranial morphology are available only for one. We describe the extema1 morphology, oral disc and chondrocranial anatomy of the larvae of Eupsophus queulensis. The characteristics of E. queulensis tadpoles are compared with those of other Eupsophus larvae.
