The Dendropsophus decipiens clade comprises four species: D. berthalutzae, D. decipiens,D. haddadi, and D. oliveirai. Tadpoles of these species were described, but data on theirinternal morphology are lacking. We provide the first description of the buccopharyngealanatomy, chondrocranial morphology, and cranial, hyoid and hyobranchial musculature ofthe tadpole of D. decipiens. Larvae of D. decipiens are characterized by the absence of lingual papillae, presence of fan-like papilla on the buccal floor, presence of a single-elementsuprarostral cartilage, presence of a small triangular process at the basis of the processusmuscularis, m. levator mandibulae lateralis inserted on the nasal sac, and m. subarcualisrectus II-IV with a single, continuous slip. Tadpoles are likely macrophagous, although notas specialized as those of other species of the genus, suggesting some degree of diversification on the feeding habits within Dendropsophus.
