The tadpole of Hypsiboas leptolineatus (Braun and Braun, 1977), a species in the Hypsiboas polytaenius clade (Anura; Hylidae)
Both, C.;Kwet, A.;Solé, M.;
Brazilian Journal of Biology , 2007, DOI: 10.1590/S1519-69842007000200016
Abstract: the larval morphology of hypsiboas leptolineatus was studied. the tadpole has an ovoid body in lateral view, wider than deep; snout rounded with dorsal reniform nostrils; spiracle sinistral with lateral wall attached to body; anal tube dextral; tail fins convex with acuminate tip; oral disc ventral; labial tooth row formula is 2(2)/3(1); moderately developed beaks with serrated jaw sheaths. these external oral features are compared with those of the known tadpoles in the hypsiboas polytaenius clade. the oral cavity was studied using an electron microscope. life history aspects are commented.
Tadpole and advertisement call of Hypsiboas crepitans (Amphibia: Anura: Hylidae) from Bahia State, Brazil, and taxonomic regards  [PDF]

Boletim do Museu Paraense Emílio Goeldi : Ciências Naturais , 2008,
Abstract: The tadpole and advertisement call of Hypsiboas crepitans are described from Serra S o José, State of Bahia, Brazil. Three multipulsed notes composed the advertisement call; the call duration was approximately 0,51 s and the dominant frequency 0,80 kHz. When we compared the advertisement call of H. crepitans from Bahia with specimens from other localities in Colombia and Panama, we found differences in the dominant frequency: the specimens from Bahia presented higher dominant frequency than the one from Colombia and much lower than the specimens from Panama. These differences could corroborate the hypothesis that there is another species or a complex of species in the Amazonian region presently named as Hypsiboas crepitans.

Skeletal development and adult osteology of Hypsiboas pulchellus (Anura: Hylidae)  [cached]

Acta Herpetologica , 2012,
Abstract: Osteological and skeletal characters have long been proven to be particularly informative in taxonomic and systematic research. Furthermore, ossification sequences are assumed to be a potential tool to investigate developmental states and developmental modes of fossil and extant skeletal specimens. Herein, we provide a detailed account on adult osteology and skeletogenesis in the Montevideo treefrog, Hypsiboas pulchellus (Anura: Hylidae) based on evaluation of a series of cleared and stained specimens. A consensus sequence of ossification, i.e., the order of appearance of mineralized elements until early metamorphosis could be determined as (parasphenoid, presacral vertebrae I-VII, frontoparietal, exoccipital) – transverse processes of presacral vertebrae I-VIII – sacral vertebra – (humerus, radioulna, ilium, femur, tibiofibula, scapula) – (cleithrum, clavicle, coracoids, metacarpals, tarsals, metatarsals, phalanges, hypochord) – (prootic, angulosplenial, dentary, maxilla, premaxilla, squamosal). Comparing the state of mineralized elements in individual specimens, a number of skeletal elements, including the exoccipital, frontoparietal, parasphenoid and prootic, as well as elements of the shoulder and pelvic girdles, and the phalanges, were found to vary intraspecifically regarding the relative time of their ossification within the ossification sequence.
An unusual reproductive mode in Hypsiboas (Anura: Hylidae)
Moura, Mário Ribeiro de;Motta, Ana Paula;Feio, Renato Neves;
Zoologia (Curitiba) , 2011, DOI: 10.1590/S1984-46702011000100021
Abstract: we report an unusual reproductive behavior of hypsiboas pardalis (spix, 1824). species belonging to this genus usually are known to reproduce in lentic water bodies, with the development of exotrophic tadpoles. herein, the bromeligenous behavior is reported for the first time in hypsiboas wagler, 1830. although this reproductive behavior has been observed more than once here, we believe that it is not typical of hypsiboas, being better characterized as an unusual reproductive mode for hypsiboas, indicating the presence of plasticity in the reproductive modes of h. pardalis
Amphibia, Anura, Hylidae, Hypsiboas raniceps Cope, 1862: Distribution extension  [PDF]
Zina, J.,, F. P.,Prado, C. A. P.
Check List , 2010,
Abstract: Hypsiboas raniceps is a large treefrog typically found in the Cerrado and Caatinga biomes. Here we provideinformation about new records of this species in the Atlantic Forest and raise some hypotheses that could explain the laterecord of this species in this biome.
Description of the tadpole of Scinax auratus (Wied-Neuwied) (Anura, Hylidae)
Alves, Ana C. R.;Gomes, Márcia dos Reis;Silva, Sergio P. de Carvalho e;
Revista Brasileira de Zoologia , 2004, DOI: 10.1590/S0101-81752004000200026
Abstract: scinax auratus occurs in the atlantic rain forest of northeastern brazil. it is found inside the forest on outcrop rocks and in open areas along the forest border. the tadpoles are found in temporary ponds. herein we describe the tadpole of s. auratus and compare it with those of other related species of the genus scinax. the diagnostic characteristics of the tadpole of s. auratus include aspects of the general colour and forms of the body, tail, third posterior tooth row, and jaw sheaths.
The tadpole of Osteocephalus cabrerai (Anura: Hylidae) from central Amazonia, Brazil

Phyllomedusa : Journal of Herpetology , 2011,
Abstract: Herein we describe the tadpoles of Osteocephalus cabrerai based on 37 individuals of eight different development stages. We provide comments on spawning sites and breeding period, and compare these tadpoles with those of congeners. The tadpole of O. cabrerai (Stage 39) is characterized by an ovoid body, elongated in lateral view and oval in dorsal view. The snout is rounded, the nostrils oval and the eyes lateral. The tail length is 67% of total length. The larva has a single, sinistral spiracle that is ventrolateral in position. The short vent tube is dextral and attached to the ventral fin. The anteroventral oral disc has marginal and submarginal papillae and a labial tooth row formula 2(2)/6(1). Tadpoles inhabit streams in terra firme forest.
Distribution, vocalization and taxonomic status of hypsiboas roraima and h. angelicus (Amphibia: Anura: Hylidae)

Papéis Avulsos de Zoologia (S?o Paulo) , 2011, DOI: 10.1590/S0031-10492011000200001
Abstract: the distribution of the poorly known hylid frog hypsiboas roraima duellman & hoogmoed, on the guiana shield is redefined, including new records from venezuela. the advertisement call of this species is analyzed and hypsiboas angelicus myers & donnelly is associated as a junior synonym of h. roraima.
