Abstrakt: The genus Phyllodytes comprises 15 species, ten of them having their tadpole external morphology described in the literature. However, there are few descriptive studies on chondrocranium and hyobranchial skeleton. In this work, we describe the chondrocranium and hyobranchial skeleton of Phyllodytes larvae and discuss shared features and interspecific variation. Our findings suggest that the skeletal morphology is mostly conserved in the genus, with common features including a single suprarostral cartilage, short infrarostral cartilages, and overall short trabecular horns. Main intrageneric variations include the arrangement of the ascending process, the presence of larval otic process, and the configuration of the crista parotica. These variations are not correlated with the phylogenetic structure of the genus. Some distinctive aspects of P. praeceptor and P. gyrinaethes are also described in tadpoles of Osteopilus ocellatus, and could be related to oophagous habits in these tadpoles.
