“…THE FAMILY Hylodidae includes the genera Crossodactylus Dú meril and Bibron, 1841 (14 species), Hylodes Fitzinger, 1826 (24 species), and Megaelosia Miranda- Ribeiro, 1923 (7 species;Frost 2014;Pimenta et al 2014). Crossodactylus is composed of stream-dwelling diurnal frogs that are distributed from the state of Alagoas in northeastern Brazil, south to the state of Rio Grande do Sul in southern Brazil, and further into southern Paraguay and northern Argentina Caramaschi 1993 ''1992'';Frost 2014).…”

“…Vocal sacs have been reported as absent in C. aeneus and C. trachystomus (Müller, ) and single, subgular in C. aeneus, C. bokermanni, C. cyclospinus, C. dantei, C. gaudichaudii, C. lutzorum, C. schmidti , and C. trachystomus (Lynch, ; Pimenta, Cruz, & Caramaschi, ; Pimenta et al, ). Subtle bilobular expansions have been reported only in C. boulengeri (Pimenta, Wachlevski, & Cruz, ), C. caramaschii (Bastos & Pombal, ), and C. dispar (Pimenta et al, ). Nevertheless, study of internal vocal sac anatomy revealed the presence of paired, lateral vocal sacs in C. aeneus , C. boulengeri , C. cyclospinus , C. dantei , C. dispar , C. gaudichaudii , C. grandis , and C. schmidti .…”

“…This is probably why most species of Crossodactylus have been reported to have single, subgular sacs in the taxonomic literature. Vocal sacs have been reported as absent in C. aeneus and C. trachystomus (M€ uller, 1924) and single, subgular in C. aeneus, C. bokermanni, C. cyclospinus, C. dantei, C. gaudichaudii, C. lutzorum, C. schmidti, and C. trachystomus (Lynch, 1971;Pimenta, Cruz, & Caramaschi, 2014;Pimenta et al, 2015). Subtle bilobular expansions have been reported only in C. boulengeri (Pimenta, Wachlevski, & Cruz, 2008), C. caramaschii (Bastos & Pombal, 1995), and C. dispar (Pimenta et al, 2014).…”

Anuran vocal sacs are elastic chambers that recycle exhaled air during vocalizations and are present in males of most species of frogs. Most knowledge of the diversity of vocal sacs relates to external morphology; detailed information on internal anatomy is available for few groups of frogs. Frogs of the family Hylodidae, which is endemic to the Atlantic Forest of Brazil and adjacent Argentina and Paraguay, have three patterns of vocal sac morphology-that is, single, subgular; paired, lateral; and absent. The submandibular musculature and structure of the vocal sac mucosa (the internal wall of the vocal sac) of exemplar species of this family and relatives were studied. In contrast to previous accounts, we found that all species of Crossodactylus and Hylodes possess paired, lateral vocal sacs, with the internal mucosa of each sac being separate from the contralateral one. Unlike all other frogs for which data are available, the mucosa of the vocal sacs in these genera is not supported externally by the mm. intermandibularis and interhyoideus. Rather, the vocal sac mucosa projects through the musculature and is free in the submandibular lymphatic sac. The presence of paired, lateral vocal sacs, the internal separation of the sac mucosae, and their projection through the m. interhyoideus are synapomorphies of the family. Furthermore, the specific configuration of the m. interhyoideus allows asymmetric inflation of paired vocal sacs, a feature only reported in species of these diurnal, stream-dwelling frogs.

“…Since then, there has been an increase in species inventories performed throughout the state, improving the knowledge about the composition and distribution of the state's amphibian fauna (e.g., Almeida-Gomes et al, 2008, 2014Carvalho-e-Silva et al, 2008;Siqueira et al, 2011a, b;Salles et al, 2009;Silva-Soares et al, 2010;Vrcibradic et al, 2011;Martins et al, 2012Martins et al, , 2014Telles et al, 2012;Bittencourt-Silva & Silva, 2013;Pontes et al, 2015). Additionally, several species have been added to the state's amphibian list, either through reports of new occurrence records (e.g., Vrcibradic et al, 2006;Silva-Soares et al, 2009;Silveira et al, 2010;Caram et al, 2011;Pederassi et al, 2015), or through descriptions, revalidations or reassessments of taxa (e.g., Carvalho-e-Silva & Carvalho-e-Silva, 2005;Caramaschi & Pombal, 2006;Canedo & Pombal, 2007;Pombal et al, 2008;Prado & Pombal, 2008;Silva & Alves-Silva, 2008;Carvalho-e-Silva et al, 2009Targino et al, 2009;Pombal, 2010;Pombal & Izecksohn, 2011;Weber et al, 2011;Silva & Alves-Silva, 2011;Nunes et al, 2012;Silva & Ouvernay, 2012;Dias et al, 2013;Caramaschi et al, 2013;Pimenta et al, 2014;Hepp et al, 2015).…”

The amphibians of the state of Rio de Janeiro, Brazil: an updated and commented list

2018

View full text Add to dashboard Cite

The amphibian fauna of the state of Rio de Janeiro, in southeatern Brazil, is characterized by high species richness and rates of endemism, and is still insufficiently known. A first list of amphibian species with occurrence in the state was published in 2004 and reported 166 taxa, but since then many new records, descriptions of new taxa, and revalidations and synonymizations of species have consistently improved the knowledge about the state’s amphibian biodiversity. Thus, a review and update of that list was deemed necessary. We herein present an updated and commented list of amphibian species occurring in the state of Rio de Janeiro based on a survey of the literature. We recorded the occurrence of a total of 201 species of amphibians (197 anurans and four caecilians) in Rio de Janeiro, with 54 of them (ca. 27%) considered to be endemic of the state. Our study presents an increase in species richness of 21% since the publication of the previous list, indicating a consistent advance in knowledge of the composition of the amphibian fauna in the state. In spite of its relatively small territorial extension (total area ca. 43,800 km²), the state of Rio de Janeiro contains nearly 20% of the amphibian species known to occur in Brazil and around 40% of those occurring in the Atlantic Forest biome. Thus, that state constitutes an important reservoir of amphibian biodiversity in the Atlantic Forest biome and in Brazil, as a whole.
