We describe the tadpole of Sphaenorhynchus caramaschii. It differs from tadpoles of other species of Sphaenorhynchus in having a short spiracle, submarginal papillae, and alternating short and large marginal papillae in the oral disc. Some larval characteristics, like morphology and position of the nostrils, length of the spiracle, and size of the marginal papillae on the oral disc are discussed for tadpoles of other species of Sphaenorhynchus.39042270282Almeida, S.C., Maffei, F., Rolim, D.C., Ubaid, F.K., Jim, J., Amphibia, Anura, Hylidae, Sphaenorhynchus caramaschii, Distribution extension in State of São Paulo, Brazil (2008) Check List, 4, pp. 439-441Altig, R., McDiarmid, R.W., Body plan, development and morphology (1999) Tadpole: The Biology of Anuran Larvae, pp. 24-51. , University of Chicago Press, Chicago and LondonAmiet, J.-L., Les Cardioglossa camerounaises (1972) Science et Nature, 114, pp. 11-24Antunes, A.P., Faivovich, J., Haddad, C.F.B., A new species of Hypsiboas from the atlantic forest of southeastern Brazil (Amphibia, Anura, Hylidae) (2008) Copeia, 1, pp. 179-190. , http://dx.doi.org/10.1643/ch-06-163Barrio, A., Cloricia fisiologica en batracios Anuros (1965) Physis, 25, pp. 69137-69142Benício, R.A., Silva, G.R., Fonseca, M.G., Amphibia, Anura, Hylidae, Sphaenorhynchus lacteus (Daudin, 1800): First record of the genus and species for the State of Piauí, Brazil (2011) Checklist, 7, pp. 196-197Bertoluci, J., Rodrigues, M.T., Utilizac¸ão de habitats reprodutivos e microhabitats de vocalizac¸ão em uma taxocenose de anuros (Amphibia) da Mata Atlântica do sudeste do Brasil (2002) Papéis Avulsos de Zoologia, 42, pp. 287-297. , http://dx.doi.org/10.1590/s0031-10492002001100001Blackburn, D.C., A new species of Cardioglossa (Amphibia, Anura, Arthroleptidae) endemic to Mount Manengouba in the Republic of Cameroon, with an analysis of morphological diversity in the genus (2008) Zoological Journal of the Linnean Society, 154, pp. 611-630. , http://dx.doi.org/10.1111/j.1096-3642.2008.00397.xBokermann, W.C.A., Duas novas espécies de "Sphaenorhynchus" (Amphibia, Hylidae) (1966) Revista Brasileira de Biologia, 26, pp. 15-21Bokermann, W.C.A., Duas novas espécies de Sphaenorhynchus da Bahia (Anura, Hylidae) (1973) Revista Brasileira de Biologia, 33, pp. 589-594Caramaschi, U., Descric¸ão do girino de Sphaenorhynchus surdus (Cochran, 1953) (Anura, Hylidae) (2010) Boletim Do Museu de Biologia Mello Leitão (Nova Série), 27, pp. 67-74Caramaschi, U., Almeida, A.P., Gasparini, J.L., Description of two new species of Sphaenorhynchus (Anura, Hylidae) from the State of Espírito Santo, Southeastern Brazil (2009) Zootaxa, 2115, pp. 34-46Cisneros-Heredia, D.F., McDiarmid, R.W., Revision of the characters of Centrolenidae (Amphibia, Anura, Athesphatanura), with comments on its taxonomy and the description of new taxa of glassfrogs (2007) Zootaxa, 1572, pp. 1-82Cruz, C.A.G., Observac¸ões sobre o girino de Sphaenorhynchus planicola (Lutz & Lutz, 1938).
