The Tadpole of Hyla nahdereri Lutz and Bokermann, 1963

The Hyla marmorata group is widely distributed in South America and currently includes eight species, most of them characterized by a dorsal color pattern that resembles lichenous tree bark. The recognition of species taxonomic limits have been problematic within the H. marmorata group, apparently due to geographical variability within the recognized taxa and lack of distributional information from some important regions. Gomes and Peixoto (1991a) suggested the potential importance of larval characters as diagnostic traits for this group of Hyla, but the tadpoles of only three of the eight species have been described. Hyla nahdereri occurs at elevations around 800 m in the Brazilian State of Santa Catarina and is the southernmost species in the group. We describe the tadpole and feeding habits of H. nahdereri, and comment on the morphological traits that distinguish it from the tadpole of H. senicula, the geographically closest species of the H. marmorata group.
