No. of bitstreams: 0 Previous issue date: 2021-10-01; Consejo Nacional de Investigaciones Científicas y Técnicas; Vocal sacs are among the most conspicuous features of anurans and are particularly striking in casque-headed treefrogs (Hylidae: Hylinae: Lophyohylini) with their wide array of morphologies. In this paper, we assessed the anatomy of vocal sacs ...

Made available in DSpace on 2021-06-25T10:46:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-12-01; The two species of the Bokermannohyla claresignata species group (Anura: Hylidae) have not been collected for the last four decades. It is the only species group of the hyline tribe Cophomantini that has not yet been analysed genetically. Its phylogenetic position is thus uncertain, and it has a combina...

Made available in DSpace on 2021-06-25T10:57:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-03-31; True toads of the genus Rhinella are among the most common and diverse group of Neotropical anurans. These toads are widely distributed throughout South America, inhabiting a great diversity of environments and ecoregions. Currently, however, the genus is defined solely on the basis of molecular charact...

A neotype for Hyla x-signata Spix, 1824 (Amphibia, Anura, Hylidae)

The uncertain identity of Hyla x-signata Spix, 1824 has been a pervasive problem in the taxonomy of the genus Scinax. A species supposedly distributed from northeastern Brazil northwards to Colombia and Venezuela, described in a few lines without much information and with an accompanying figure, and its type specimen lost during World War II, combined to produce a curious situation. Twenty-one of the 39 species...

A new species of the Hypsiboas pulchellus Group from the Serra da Mantiqueira, ...

A new species of the Hypsiboas pulchellus group is described from the Mantiqueira range, in the Munic ́ıpio de Rio Preto, State of Minas Gerais, Brazil. We describe adults, tadpoles, and the advertisement call. The new species is morphologically similar to H. freicanecae, a species known from a few localities in the states of Alagoas and Pernambuco, northeastern Brazil, ~1640 km north. Adults differ from H. fre...

The Green Clade grows: A phylogenetic analysis of Aplastodiscus (Anura; Hylidae)

Made available in DSpace on 2018-12-11T17:01:45Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-04-01; Green tree frogs of the genus Aplastodiscus occur in the Atlantic Forest and Cerrado biomes of South America. The genus comprises 15 medium-sized species placed in three species groups diagnosed mainly by cloacal morphology. A phylogenetic analysis was conducted to: (1) test the monophyly of these speci...
