Abstract
The tadpole of the endemic Chilean frog Eupsophus nahuelbutensis is described. The description includes external morphology, chondrocranium, and comments on natural history and systematics. This tadpole is endotrophic-nidicolous and unpigmented, resembling other larvae of the genus. In spite of its endotrophy and some typical traits of nidicolous tadpoles, the larva of E. nahuelbutensis does not differ significantly from a generalized exotrophic larvae. In addition, ecomorphological and biological characteristics of the tadpole of E. nahuelbutensis are discussed and compared with other members of Eupsophus.References
