Este trabalho tem como objetivo fornecer informações sobre a diversidade de parasitas associados a Proceratophrys aridus Cruz, Nunes & Juncá, 2012 e descrever e comparar a helmintofauna deste hospedeiro com as demais espécies inventariadas do gênero. Os espécimes foram coletados manualmente entre 2012 e 2016 em dez localidades do Nordeste do Brasil. Um total de 37 P. aridus foram necropsiados e analisados para endoparasitas, dos quais 22 foram parasitados com pelo menos um táxon helminto. Para verificar a similaridade entre as comunidades parasitas, foi realizada uma análise de agrupamento utilizando o índice de Sorensen. Para esta análise, foi construída uma matriz com dados de presença e ausência para as espécies de helmintos relacionados ao táxon Odontophrynidae. Um total de 867 helmintos foram recuperados, incluindo nematóides,...

We present and discuss the type-host and localities, the current taxonomic status, remarks on morphological features, biological cycle, and new records of these parasites. Nine hundred and seventy-eight anurans of four families (Bufonidae, Hylidae, Microhylidae, and Leptodactylidae) were collected during four expeditions in a private forested area from Northwest of São Paulo state. The richness of metazoan parasites was composed of nematodes (21), acanthocephalans (2), digeneans (18), monogeneans (1), cestodes (1), and oligochaetes (1), resulting in 44 taxa that are presented with their respective prevalence and the range of abundance in host populations. Among these parasites, nine were found in immature stages which usually complete their life cycle in fishes, snakes, birds or mammals, attesting the trophic relati...

Aunque es una familia bien conocida, falta conocimiento sobre la diversidad de su hospedadores. En este documento, ampliamos el conocimiento de la fauna parasitaria de anuros de la familia Hylodidae y la distribución geográfica de tres especies de nematodos cosmocercidos (Cosmocerca brasiliensis Travassos, 1925, Cosmocercoides sauria Ávila, Strüssmann & Silva, 2010 y cosmocercid) encontrados en dos ranas torrentes macho Hylodes heyeri Haddad Pombal & Bastos, 1996. Nuestro reporte incluye nuevos datos sobre la distribución geográfica y la morfología de los parásitos cosmocercidos y aclara aún más las interacciones parasitarias de los anfibios neotropicales.

Because of the high morphological similarity and an unknown number of undescribed taxa among the species of this group, we did an extensive search for character distribution within all nominal taxa. Herein we describe Rhinella parecis sp. nov. a new species from Southern Brazilian Amazon. We provide a morphological diagnosis, morphometric comparisons with similar species, and a molecular phylogenetic hypothesis on the relationships of the new species. Rhinella parecis sp. nov. is assigned to the R. margaritifera group and differs from others species by snout-vent length ranging 40.7–53.5 mm in males (n=12) and 44.9–54.8 mm in females (n=4), snout rounded in dorsal view, acute with fleshy ridge extending to tip of snout in lateral view, canthal and pre-orbital crests absent, supra-orbital, parietal and supra-tympanic crests present and low, dorsolateral row of tube...

Herein, we describe the acoustic parameters of Teratohyla midas (Anura, Centrolenidae), with notes on distribution in the Brazilian states of Acre, Amapá, Amazonas, and Pará. The typical advertisement call of T. midas consists of a single pulsed note, with 3 pulses emitted in a very short emission. The advertisement calls of T. midas from Ecuador and French Guiana are distinct from those reported here.

Overall, 227 individuals (185 larvae, 32 nymphs, 7 adults females and 3 males) identified as follow: Amblyomma dissimile, Amblyomma rotundatum, Amblyomma sp. larvae, Ornithodoros mimon, Ornithodoros rietcorreai, and an Ornithodoros sp. Herein, we present 25 new tick-host associations, thus contributing to the knowledge on tick-fauna associated to amphibians and reptiles from Brazilian northeast.

Resumo Os recursos alimentares representam uma porção importante do nicho trófico, sendo um determinante importante na estruturação de comunidades em qualquer grupo filogenético. Dessa forma, objetivamos contribuir com informações ecológicas sobre a composição da dieta, amplitude de nicho trófico e tamanho corpóreo de Pseudopaludicola pocoto em uma área de Caatinga do nordeste brasileiro. As coletas foram realizadas durante as estações de seca (setembro de 2015) e chuvosa (fevereiro de 2016), quando foram coletados e analisados 120 espécimes de P. pocoto. Registramos a dieta do período seco composta por treze categorias de presas, sendo Coleoptera e Hemiptera as categorias de maior importância relativa. A amplitude de nicho trófico (Bsta = 0,18) indica que P. pocoto é consumidor especialista. Todos os indivíduos coletados durante a estação chuvosa não apresentaram conteúdo estomacal. Além disso, não foram observadas diferenças significativas entre os tamanhos corpóreos de machos e fêmeas. Futuros trabalhos que abordem a reprodução dessa espécie são estimulados, pois podem contribuir para a compreensão de fenômenos como a ausência de conteúdo estomacal durante o período reprodutivo e, por fim, comprovarem ou não a hipótese de estivação nessa espécie.

Herein, we presented data for Rhinella gildae based on recently collected specimens from its type locality. We provide patterns of morphological variation, measurements, advertisement and release calls and infer the phylogenetic position of R. gildae. The species geographical distribution was updated, occurring in two Amazonian localities in Maranhão state, and Cerrado areas in Maranhão and Tocantins states and also in a rainforest enclave inside Caatinga domain in Ceará state.

This study provides additional data on morphometric and molecular phylogenetic position inferred from the nuclear ribosomal gene 28S (partial). DNA sequences were isolated from Haplometroides intercaecalis Silva, Ferreira and Strüssmann, 2007 found in one specimen of Phalotris matogrossensis Lema, D'Agostini and Cappellari, 2005. Five digenean specimens were recovered from the esophagus of this snake, and four specimens were used for morphometrical studies and one specimen for molecular analysis. Phylogenetic analysis using maximum likelihood and Bayesian methods was conducted with sequences available for the order Plagiorchiida and its phylogenetic position places H. intercaecalis among the brachycoeliids Brachycoelium (Dujardin, 1845) Stiles and Hassall, 1898 and Parabrachycoelium Pérez-Ponce de León, Mendoza-Garfias, Razo-Mendivil and Parra-Olea, 2011, and the mesocoeli...

The species richness was 6 helminth taxa, cystacanths of Acanthocephala and 5 species nematodes: Aplectana membranosa, Parapharyngodon silvoi, Physaloptera spp., Raillietnema spectans and unidentified nematode larvae. The overall prevalence was 88.6%, with an average intensity of infection 123.7 ± 26.3. The nematode Raillietnema spectans presented higher prevalence and was most abundant (d = 0.670). Host body size did not influence the intensity of infection nor species richness of helminths. This study increases the knowledge the diversity of helminth fauna associated with Dermatonotus muelleri from northeastern Brazil, extends the record of hosts and the geographic distribution of these nematodes.

Here we report a new Brazilian state record for the species, improving our knowledge of its geographic distribution. On 15 May of 2008, one female specimen was collected at Serra do Santo Expedito, Aripuanã municipality, state of Mato Grosso, Brazil. This is the first record of this species for the state of Mato Grosso and extends its distribution ca. 300 kilometers from the nearest localities presented in literature.

Leposternon polystegum Duméril, is a widespread species distributed in the Amazon, Atlantic Forest, Cerrado, and Caatinga biomes (Porto et al., 2000; Ribeiro et al., 2011). The diet is composed mainly by ants, termites, and coleopteran larvae (Barros-Filho & Valverde, 1996; Gomes et al., 2009).
