A new genus and two new species of minute leptodactylid frogs from northern South America, with comments upon Phyzelaphryne (Amphibia: Anura: Leptodactylidae) Naturalis
Hoogmoed, M.S.; Lescure, J..
The synonymisation of Phyzelaphryne miriamae Heyer with Eleutherodactylus nigrovittatus Andersson is denied and it is shown that both species are quite distinct in numerous characters. A new genus (Adelophryne) of minute leptodactylid frogs with pointed discs on the toes and a distinctly reduced fourth finger, containing two new species (A. adiastola spec. nov. and A. gutturosa spec. nov.) is described from northern South America. A key to separate the diminutive leptodactylid frogs with pointed toetips is given. The relationships of the new genus are not clear, but possibly are with one of the species groups of Eleutherodactylus, of the subfamily Eleutherodactylinae.

A new species of Telmatobufo (Schmidt 1852) (Anura, Calyptocephalellidae) from a remnant of the Maulino Forest, central Chile Gayana
Cuevas,César C.
A new species, Telmatobufo ignotus, from the Reserva Nacional Los Queules, Cauquenes Province, central Chile is described herein. The new taxon is hypothesized based on a new combination of adult, larval, and chromosomal characters. The new species present the more septentrional distribution on the coastal range and a very restrictive distribution area compared to its congeners; because of this, taxonomic and conservation comments are discussed and advanced.

A simplified table for staging embryos of the pipid frog Pipa arrabali Anais da ABC (AABC)
ARAÚJO,OLÍVIA G.S.; HADDAD,CÉLIO F.B.; SILVA,HÉLIO R. DA; PUGENER,LOURDES A..
ABSTRACT Pipa is a Neotropical genus of frogs that dwell in freshwater environments. It includes four species that lack free-swimming larvae (P. aspera, P. arrabali, P. pipa, and P. snethlageae) and three with tadpoles (P. carvalhoi, P. myersi, and P. parva). Developmental tables such as the one proposed by Nieuwkoop and Faber might be useful for Pipa species with tadpoles. However, for the other Pipa species, to determine stages by this table or by any of the tables already prepared for frogs without tadpoles (e.g., Crinia nimbus, Eleutherodactylus coqui, and Oreobates barituensis) is impossible. By using embryonic, juvenile, and subadult specimens, we generated a staging table for P. arrabali, from the moment limb buds were first observed until birth,...

Advertisement call and female sexual cycle in Uruguayan populations of Physalaemus henselii (Anura, Leiuperidae) Iheringia, Sér. Zool.
Maneyro,Raúl; Núñez,Diego; Borteiro,Claudio; Tedros,Marcelo; Kolenc,Francisco.
Physalaemus henselii (Peters, 1872) is a little known leiuperid frog that has not been studied since the 1960’s. Herein, we redescribe its advertisement call, and assess the female sexual cycle and the reproductive period on the basis of the macroscopic analysis of the ovaries and field observations. The Ovarian Size Factor (OSF) was calculated. The study was made in Departamento de Rivera, northern Uruguay. The advertisement call consists of short (177 ± 21ms), multipulsed (20 ± 3 pulses/note) notes, with a note repetition rate of 1.57 ± 0.13 notes/s. Physalaemus henselii has a female sexual cycle with unimodal distribution of gravid females, which are present from February to September. The OSF and the ratio "females with mature oocytes / females without...

Advertisement calls of Bolivian species of Scinax (Amphibia, Anura, Hylidae) Naturalis
Riva, Ignacio de la; Márquez, Rafael; Bosch, Jaime.
The advertisement calls of eight Bolivian species of Scinax are described including information on the calling behaviour of each species. A characteristic audiospectrogram and oscillogram are presented for each species, as well as numerical information about the spectral and temporal features of the calls. Two phenograms based on the characteristics of the mating calls are constructed, the first one using a traditional multivariate technique (UPGMA) and the second one using audiospectrogram correlation, a new technique that allows holistic comparisons of single vocalizations.

Alimentação e variação sazonal na freqüência de capturas de anuros em duas localidades do Brasil central Zoologia
Moreira,Glória; Barreto,Larissa.
The feeding ecology and the sazonal variation in capture frequencies of anurans in two localities of Central Brazil was studied. The anuran capture frequencies were analysed counting specimen numbers collected in pitfall traps during the dry and rainy seasons. Anurans were caught more frequently during the rainy season. The diet of adults Proceratophrys sp., Eleutherodactylus sp., Bufo paracnemis Lutz, 1925, and Physalaemus cuvieri Fitzinger, 1826 were studied through the analysis of individual stomach contents. Results showed that the type of diet varied among the species studied.

Amphibians of the Parque Nacional da Restinga de Jurubatiba, a sandy coastal environment in southeastern Brazil Biota Neotropica
Carmo,Luiz Fernando; Miguel,Ingrid Ribeiro; Pinna,Pedro H.; Fernandes,Daniel Silva; Woitovicz-Cardoso,Manoela.
Abstract: We provide an inventory checklist of the amphibians from Parque Nacional da Restinga de Jurubatiba (PNRJ), a sandy coastal environment in southeastern Brazil. As a result of three years of surveys, from August 2013 to June 2016, a total of 36 amphibians species were recorded - one Gymnophiona (Typhlonectidae) and 35 species of five anuran families: Bufonidae (2 species), Craugastoridae (1), Hylidae (21), Leptodactylidae (8), and Microhylidae (3). One specie is reported for the first time for the restinga ecosystem (Chthonerpeton braestrupi) and 24 species were recorded for the first time to the PNRJ. This result reinforces the importance of long-term studies for accurate knowledge of the biodiversity. Considering that the biodiversity of the...

Rossa-Feres,Denise de Cerqueira; Sawaya,Ricardo Jannini; Faivovich,Julián; Giovanelli,João Gabriel Ribeiro; Brasileiro,Cinthia Aguirre; Schiesari,Luis; Alexandrino,João; Haddad,Célio Fernando Baptista.
A última lista de espécies do Estado de São Paulo foi atualizada, totalizando 236 espécies de anfíbios, das quais 230 são anuros e seis são Gymnophiona. Foram removidos da lista Bokermannohyla gouveai e Sphaenorhynchus surdus por não ocorrerem no Estado de São Paulo. O número de espécies de anuros registrado representa 27% da riqueza de espécies do país e um aumento de 31% em relação ao número de espécies registradas para o Estado em 1998, demonstrando que, a despeito do Estado de São Paulo ser a região brasileira onde os anuros foram mais estudados, o número de espécies conhecidas deve aumentar nos próximos anos. Foram evidenciadas duas lacunas geográficas importantes: a região sudoeste do Estado, principalmente na bacia hidrográfica do rio Paranapanema e...

Anuran amphibians' diversity in a northwestern area of the Brazilian Pantanal Biota Neotropica
Pansonato,André; Mott,Tamí; Strüssmann,Christine.
In the Pantanal, the largest continuous floodplain in the world, the diversity and distribution of anuran amphibians vary in and across distinct subregions and distinct habitats occurring along inundation gradients. Permanent and natural aquatic habitats are relatively scarce in the Pantanal, and occurrence of temporary aquatic habitats varies seasonally, depending on rains. We here present results of evaluations of anuran's species richness and abundance in a seasonally flooded area in the northwestern section of the Pantanal (Fazenda Baía de Pedra, Cáceres municipality, state of Mato Grosso, Brazil), comparing values obtained in 10 plots systematically distributed over 5 km² with those obtained in additional aquatic plots in the study area. Data were...

Anuran larvae as prey and hosts of invertebrates in neotropical aquatic habitats RChHN
Gambale,Priscilla Guedes; Batista,Vinícius Guerra; Oda,Fabrício Hiroiuki; Campos,Renata Mayara; Takemoto,Ricardo Massato; Bastos,Rogério Pereira.
BACKGROUND: Biotic processes, such as predation and parasitism events, are crucial for answering questions in ecology and evolution. Here, we report predation and ectoparasitism events of invertebrates upon tadpoles in aquatic habitats of southern Brazil. FINDINGS: Four lentic water bodies were sampled twice a month (December 2012 to March 2013). Those water bodies were located in the Diamante do Norte County, State of Paraná, southern Brazil. The tadpoles, Dendropsophus aff. minutus, Hypsiboas raniceps, Scinax fuscovarius, Physalaemus cuvieri and Elachistocleis bicolor were observed being predated by six different invertebrate predators. However, Leptodactylus fuscus and Pseudis sp. were also recorded on the same water bodies and were not observed being...

Anurans of the Parque Estadual do Mirador, a remnant of Cerrado in the state of Maranhão, Northeastern Brazil Biota Neotropica
Andrade,Etielle Barroso de; Weber,Luiz Norberto; Leite,José Roberto de Souza Almeida.
Abstract The Cerrado is one of the most threatened biomes in Brazil. It is estimated that much of its original vegetation has been replaced by some type of human use. This is quite worrying, mainly in the northern part where the number of wildlife inventories is insufficient and creates the false impression of low diversity in the region. The Parque Estadual do Mirador-PEM, located in the south-central region of the state of Maranhão, presents vegetation typical of the Cerrado biome and corresponds to one of 46 priority areas for conservation in the state. Herein, we describe the species richness and composition of the anurofauna from the PEM and analyze the influence of different types of vegetation in its formation. Our inventory was conducted from...

Anuros da Estação Ecológica de Santa Bárbara, um remanescente de formações abertas de Cerrado no estado de São Paulo Biota Neotropica
Araujo,Cybele de Oliveira; Corrêa,Décio Tadeu; Santos,Selma Maria de Almeida.
Apesar de São Paulo ser o estado do país que possui o maior conhecimento sobre sua fauna de anuros, ainda persistem consideráveis vazios amostrais, sobretudo nos remanescentes de Cerrado do estado. Somente 0,5% deste bioma encontram-se protegidos por unidades de conservação no estado e os fragmentos remanescentes sofrem ameaças que incluem o isolamento, risco de incêndios e invasão por espécies vegetais exóticas. Neste contexto, o objetivo deste estudo foi gerar informações sobre as espécies de anuros presentes na Estação Ecológica de Santa Bárbara, um dos poucos remanescentes com formações abertas de Cerrado da bacia hidrográfica do Médio Paranapanema. O levantamento das espécies foi realizado mensalmente entre outubro/2008 a março/2009, totalizando 30...

B-chromosomes in two Brazilian populations of Dendropsophus nanus (Anura, Hylidae) Genet. Mol. Biol.
Medeiros,Lilian R.; Rossa-Feres,Denise C.; Jim,Jorge; Recco-Pimentel,Shirlei M..
We report on the presence of B-chromosomes in two populations of Dendropsophus nanus (= Hyla nana Boulenger, 1889) from São Paulo State, Brazil. Such chromosomes were observed in 4 out of 43 specimens (9.3%) and in 9 out of 15 specimens (60%) from the municipalities of Nova Aliança and Botucatu, respectively. The karyotype 2n = 30 + 1B found in D. nanus was similar to that of other species with 2n = 30 chromosomes, except for the presence of an additional small telocentric chromosome. In one specimen from Botucatu, cells with one to three extra chromosomes were observed. These B-chromosomes appeared as univalent in meiosis I and did not bear a nucleolar organizer region or exhibit constitutive heterochromatin.

Call diversity of Leptodactylus natalensis Lutz, 1930 (Anura; Leptodactylidae) Pap. Avulsos de Zool. (São Paulo)
Prado,Gustavo M.; Bilate,Marcos; Wogel,Henrique.
The extensive vocal repertoire of Leptodactylus natalensis is described. The field observations were made at three forest fragments of the Tropical Atlantic Domain, in Northeast (State of Alagoas) and Southeast (State of Espírito Santo) regions of Brazil. The vocal repertoire of L. natalensis was constituted by ten notes emitted alone or in different combinations. The several vocalizations were organized in three distinct groups according to the social context in the moment of emission. L. natalensis presents extensive diversity of acoustic signals supported by variations in duration of each note, as well as in the number and sequence of emission of different notes.
