A new nematode species of the Diplotriaenidae is described from Neotropical region. The was found infecting body cavity snake Xenodon merremii (Wagler in Spix) collected municipality Barbalha, Ceará State, Northeastern Brazil. Hastospiculum nordestinum n. sp. differs congeners by combining following characters: caudal end ornamented with lateral alae not surrounding tail and connected, supported eight pairs pedunculated papillae (three precloacal, one paracloacal, four postcloacal pairs)...

Aplectana longa n. sp. (Ascaridida: Cosmocercidae) from the small intestine of Gastrotheca microdiscus (Amphibia: Hemiphractidae) is described and illustrated. The new species characterized by combination a unique set morphological characters: 1) Large body size in both sexes; 2) Lateral alae absent; 3) Gubernaculum present, small, thin, weakly sclerotized, pointed at distal end curved proximally end, with punctiform papilla-like dilation, 4) Caudal papillae arrangement (9+1:0:6)....

Abstract During an ecological study with a near-endangered anuran in Brazil, the Schmidt’s Spinythumb frog, Crossodactylus schmidti Gallardo, 1961, we were given chance to analyze gastrointestinal tract of few individuals for parasites. In this paper, describe new species allocreadiid trematode genus Creptotrema Travassos, Artigas & Pereira, 1928, which possesses unique trait among allocreadiids (i.e., bivalve shell-like muscular structure at opening ventral sucker); represents fourth...

Ticks collected on 21 different species of amphibians and reptiles captured during 2001 to 2017 in the northeast Brazil were identified. Overall, 227 individuals (185 larvae, 32 nymphs, 7 adults females 3 males) identified as follow: Amblyomma dissimile, rotundatum, sp. Ornithodoros mimon, rietcorreai, an Herein, we present 25 new tick-host associations, thus contributing knowledge tick-fauna associated from Brazilian northeast.

Cosmocerca spp. are common nematode parasites of amphibians. We provide herein molecular data for two species and describe a new species, albopunctata n. sp., using light microscopy (cytochrome c oxidase subunit 1 - COI mtDNA). sp. can be easily distinguished from other congeneric by the combination characteristics such as body size, length spicules gubernaculum, arrangements number caudal papillae (7 + 1:1 1:6). The phylogenetic results based on partial mtDNA sequences clustered in...

The helminth fauna associated with Muller's termite frog, Dermatonotus muelleri, from the southern region of Ceará State, Brazil, was studied. species richness 6 taxa, including cystacanths Acanthocephala and 5 nematode species: Aplectana membranosa, Parapharyngodon silvoi, Raillietnema spectans, larvae Physaloptera sp., an unidentified nematode. overall prevalence 88.6%, average intensity infection 123.7 ± 26.3. spectans presented highest most abundant (d = 0.670). Host body size did not...

In this study, we report the temporal occurrence and habitat microhabitat use by anurans in two areas located one highland marsh (brejo-de-altitude) northeastern Brazil. Fieldwork was carried out between September 2011 2012. The recorded belong to 14 species distributed five families: Hylidae (six), Leptodactylidae (five), Bufonidae, Odontophrynidae Pipidae (one each). Vocalization activity seasonal concentrated wetter warmer months, but correlated rainfall only top Chapada do Araripe....

Ecology and parasitism of the lizard Tropidurus jaguaribanus (Squamata: Tropiduridae) from northeastern Brazil. Specimens were collected as part a study their use microhabitats, activity period, body temperature, diet, foraging, sexual dimorphism (in size in form), reproductive biology, parasite community composition. The preferential microhabitat species is surface rocks (saxicolous habit). has bimodal diurnal period seasonal cycle. diet composed mainly beetles ants adults juveniles....

Natural history of the rare and endangered snake Atractus ronnie (Serpentes: Colubridae) in northeastern Brazil. The habitat use, activity period, sexual dimorphism, morphological variation, reproduction diet composition this fossorial nocturnal are reported. snakes were captured between 2008–2014 Chapada do Araripe Brazil, collected by active visual searches, as well pitfall traps with drift fences. Although females larger than males, males have longer tails, scale counts differ sexes....

The knowledge of parasitic fauna in wild animals is essential for understanding the ecological conditions that determine occurrence and prevalence parasites their hosts. With exception records one Pentastomida (Cephalobaena tetrapoda Heymons, 1922) two Nematoda (Physaloptera sp. And Aspiculuris sp.), detailed information about helminth associated with jararaca Bothrops erythromelas Amaral, 1923 lacking. This species has a wide distribution Caatinga, marginal areas Cerrado Atlantic Forest....

Currently, 56 species of Parapharyngodon are known, with only 12 reported from the Neotropical realm. pereiramendoi sp. n. is described herein host anuran Corythomantis greeningi in Caatinga biome, a Brazilian semiarid region. In males present triangular oral opening four bilobed lips, each one pair distally located rounded papillae, gubernaculum absent, short V-shaped support postanal and three pairs caudal while females have postbulbar excretory pore, vulva equatorial position, conical...

Abstract In this study, we investigated the infection by pulmonary parasites in water snake Helicops angulatus. We found four nymphs of pentastomide parasite Sebekia oxycephala, parasitizing two adult females H. angulatus collected municipality Rio Tinto, Paraíba, Brazil. This occurrence is likely due to directly infecting aquatic intermediate hosts, such as fish. The result study represents first record pentastomid

Abstract During a parasite survey in Brazilian amphibians from São Paulo state, Brazil, Gorgoderina parvicava Travassos, 1922 was found the urinary bladder (11 adult worms) and (five juvenile kidneys of pepper-frog Leptodactylus labyrinthicus (Spix, 1824). Parasites were examined by microscopy 28S rDNA COI gene sequenced analyzed for molecular study. The phylogenetic reconstructions resulted identical topologies with highly supported values nodes most clades using Maximum likelihood Bayesian...

The number of studies on the ecology genus Boana is vast in Brazilian biomes. Among different species this genus, B. raniceps considered a common and widely distributed species. Despite this, only few have explored Caatinga biome. In study we present information diet composition, reproduction, sexual dimorphism biome, northeastern Brazil, providing additional about natural history We observed that has generalist diet, consuming great diversity prey categories, but with numerical volumetric...

Los nematodos cosmocercidos son parásitos comunes de anfibios y reptiles. Aunque es una familia bien conocida, falta conocimiento sobre la diversidad sus hospederos.
