Descriptions of external morphology and buccal features are provided together with ontogenetic data of the tadpoles of Hylarana humeralis and Hylarana leptoglossa. These tadpoles are compared to known tadpoles of the genus Hylarana as defined by recent phylogenetic analyses here grouped in subgenera as previously proposed. The content of the subgenus Humerana is re-evaluated. The occurrence of three relevant larval characters (keratodont row formula, presence of long marginal papillae on the lower labium and presence of glands) is examined among the different subgenera and clades inferred from molecular phylogenies to assess their homogeneity regarding larval morphology. The smaller eggs of H. humeralis hatch into larger tadpoles and subsequently larger adults than the bigger eggs of H. leptoglossa. The reasons for the observed shift in size during stage 25 for these two species are briefly discussed in the light of literature data.

Based on specimens identified by DNA barcoding, we describe the tadpoles of 11 species of treefrogs (Boophis) in the Malagasy family Mantellidae. All tadpoles belong to species of the stream‐breeding clade within Boophis. Based on these and other published descriptions of Boophis tadpoles which develop in running water bodies, we tentatively distinguish three ecomorphological guilds for these larvae. Guild A, in which we describe the larvae of B. boehmei, B. reticulatus, B. pyrrhus, B. tasymena, and B. viridis which have few lotic adaptations, their oral disc width being 31–43% of body width, with a single row of 48–81 marginal papillae, and the first upper keratodont row having 58–144 keratodonts. Guild B, in which we describe the tadpoles of B. albilabris, B. madagascariensis, B. luteus, and of an undescribed species here named B. sp. aff. elenae, is intermediate, with an enlarged oral disc, an increasing number of keratodont rows and a lower height of the caudal fin. In these tadpoles, oral disc width ...
