The tadpole of Hypsiboas leptolineatus (Braun and Braun, 1977), a species in the Hypsiboas polytaenius clade (Anura; Hylidae).
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. The...
متن کاملImplementing new northernmost records to modelling the distribution of Hypsiboas caingua (Anura: Hylidae) in South America.
New northwestern records of the striped treefrog Hypsiboas caingua (Carrizo, 1991 "1990") are presented for Brazil, extending its known geographic distribution approximately 115 km northward (linear distance) of the previous northernmost record of the species. In all new localities, individuals of H. caingua were only found in calling activity under temperatures below 18°C. The species appears ...
متن کاملCytogenetic comparison of tree frogs of the genus Aplastodiscus and the Hypsiboas faber group (Anura, Hylidae).
Four species of Aplastodiscus and two species of Hypsiboas were cytogenetically compared. Aplastodiscus perviridis, A. cochranae, H. albomarginaus, and H. faber had 2n = 24 chromosomes, while A. albosignatus and A. leucopygius had 2n = 20 and 2n = 18 chromosomes, respectively. Aplastodiscus perviridis and A. cochranae had identical karyotypes, as indicated by their chromosomal morphology, the l...
متن کاملSpargana in the Neotropical frog Hypsiboas pulchellus (Hylidae) from Uruguay
We report the first record of parasitic larval tapeworms of the genus Spirometra (sparganum) in the frog Hypsiboas pulchellus. A total of 139 frogs were collected in Uruguay, and two of them presented a single sparganum (1.4%). One sparganum was found free into the coelomic cavity, and the other was located under the skin and in the coelomic cavity. The relevance of this finding in Uruguayan am...
متن کاملSexual Size Dimorphism in Relation to Age and Growth in Hypsiboas cordobae (Anura: Hylidae) from Córdoba, Argentina
—Most anurans exhibit sexual size dimorphism (SSD). This morphological variation between the sexes may be attributed to different ages at maturity, growth rate, or longevity. We present the first data on age structure and growth pattern of Hypsiboas cordobae using skeletochronology, and analyze SSD considering age-specific differences in body size based on 71 individuals. Snout-vent length (SVL...
