“…Syncope antenori has free-swimming nonfeeding tadpoles while direct development was suspected to occur in Syncope carvalhoi (Krü gel and Richter, 1995) and C. magnova (Moravec and Kö hler, 2007)-this was never proved by empirical evidence, only inferred from the relative large size and pigmentation of the eggs. On the other hand, most members of Chiasmocleis lay hundreds of small pigmented eggs and have exotrophic tadpoles (Duellman, 1978;Wogel et al, 2004;Lima et al, 2005;Oliveira-Filho and Giaretta, 2006;Rodrigues et al, 2008;Menin et al, 2011;Santana et al, 2012; P.L.V.P., personal obs. ), and species with aquatic free-swimming 3 Only a maximum likelihood topology is shown in de Sá et al (2012).…”

“…Não houve um caráter diagnóstico seguro que distinguisse os girinos de C. alagoanus dos de C. carvalhoi descritos por Wogel et al (2004), apesar disso os girinos de C. alagoanus apresentaram comprimento total médio um pouco maior que os de C. carvalhoi (17,4 contra 16,6 mm, estágio 35-36). No girino de C. ventrimaculata a nadadeira dorsal se origina após o final do corpo e a parte distal da cauda é curvada dorsalmente (Schlüter & Salas 1991), enquanto que em C. alagoanus a nadadeira dorsal teve início no final do corpo e a parte distal da cauda apresentou-se retilínea.…”

“…Cruz et al (1999) incluíram essa espécie no grupo de C. schubarti, caracterizado pela ausência ou presença apenas vestigial de membranas interdigitais. Apenas três espécies de Chiasmocleis possuem girinos conhecidos: C. carvalhoi (Wogel et al 2004) (também do grupo schubarti), C. cf. shudikarensis (Hero 1990) e C. ventrimaculata (Hero 1990, Schlüter & Salas 1991.…”

Tadpoles of Chiasmocleis alagoanus were collected from a temporary pond in a remnant of Atlantic Forest, municipal district of Maceió, Alagoas, Brazil. The tadpole presents lentic and nektonic habit. Body triangular in lateral view and oval in dorsal view; snout truncate in lateral, dorsal and ventral view. Eyes lateral and nostrils absent. Spiracle medial with wide opening. Anal tube ventral and short, with central opening, without free margin. Oral opening terminal, with marginal papillae and jaw sheaths absent, with the superior semicircular labial flaps suspended on the extremities of the mouth. Tooth rows absent. Tail length representing 59.1% of total length. In preservative the body is brown light and the viscera is partially visible. Notes on the environment and comparison with other tadpoles of the genera are provided.

“…Various authors described tadpoles in their work (Peixoto, 1987;Heyer et al, 1990;Cruz and Dias, 1991;Wogel et al, 2004;Rossa-Feres and Nomura, 2006;Nascimento and Skuk, 2006;Vieira and Arzabe, 2008), however most of these studies focus exclusively on the larval phase between stages 37 and 39.…”

The plasticity of the anurans' development is probably related to their great ecological and geographic diversity. Therefore, the understanding of environmental occupation by tadpoles is related to their morphological peculiarities. We evaluated the morphologic development of the larval phases 23, 25, 30, 37, 39 and 42 of Rhinella icterica with the aim of establishing the ratio of growth, the increase in corporal mass in relation to growth and the isometry of the corporal variables for each evaluated stage. We submitted the corporal variables to the Multivariate Allometry and the relation between these variables was evaluated using the Principal Components Analysis. We verified the isometric growth and correlation between the different variables, evaluated the growth according to the body mass and established the proportionality ratio between the corporal regions. Each corporal region evaluated presented a fixed proportionality ratio, regardless of the stage, and the size of this portion was found when its proportionality index was multiplied by the tadpole's total length. This study demonstrates that the larval phase of R. icterica presents an isometric growth with proportional development of the corporal parts regardless of the evaluated stage.Keywords: amphibian, allometry, tadpole, ratio of growth. Biometria e razão de proporcionalidade corpórea em girinos de Rhinella icterica(Anura: Bufonidae) em diferentes estágios de desenvolvimento ResumoA plasticidade do desenvolvimento dos anuros é em razão, provavelmente, da sua grande diversidade ecológica e geográfica, além de que a compreensão da ocupação do ambiente por suas larvas está relacionada às suas peculiaridades morfológicas intra e interespecíficas. Avaliamos aqui o desenvolvimento morfológico das fases larvais 23, 25, 30, 37, 39 e 42 de Rhinella icterica, objetivando estabelecer as suas razões de crescimento, o aumento da massa em relação ao crescimento e a isometria de desenvolvimento corporal para cada estágio avaliado. Para tal, submetemos as variáveis corpóreas à Alometria Multivariada, sendo o relacionamento entre essas variáveis avaliado pela análise dos Componentes Principais. Verificamos a isometria do crescimento e a correlação entre as diversas variáveis, além de avaliarmos o crescimento em função da massa corpórea e estabelecermos a razão de proporcionalidade entre as regiões corpóreas. Cada região corpórea avaliada apresentou uma razão de proporcionalidade fixa, independente do estágio, sendo o tamanho dessa região encontrada quando seu índice de proporcionalidade era multiplicado pelo comprimento total. Este estudo demonstra que a fase larvar de R. icterica apresenta crescimento isométrico com desenvolvimento proporcional das regiões corpóreas independentemente do estágio avaliado.Palavras-chave: anfíbio, alometria, girino, razão de crescimento.
