Abstract Nematodes of the genus Aplectana Railliet & Henry, 1916 are common parasites digestive tract amphibians and reptiles in Neotropical region. During a parasite survey on Boana boans (Linnaeus, 1758), we found specimens nematodes with characteristics. We observed set characteristics that differs species our study from its congeners, present describes new B. using light microscopy scanning electron microscopy. pella n. sp. has lateral alae somatic papillae males females; have equal...
Abstract Rhabdias pocoto n. sp. is herein described from the lungs of swamp frog Pseudopaludicola Magalhães, Loebmann, Nogueira, Kokubum, Baptista, Haddad & Garda, 2014, Caatinga biome in state Ceará, north-eastern Brazil. The new species characterized by a body that dilates posteriorly, six small lips (protuberances) and two rounded lateral expansions cuticular inflation on anterior end, each containing an amorphous gland-like structure inside short conical tail. Additionally, molecular...
Abstract Physaloptera Rudolphi, 1819 is a genus of nematodes that includes approximately 100 species parasitic in vertebrates around the world. From these, 30 occur Neotropical region, with nine reported from neotropical reptiles. spp. are recognized by their distinct morphology apical end and characters reproductive system. However, despite fact morphological for diagnosis have been firmly established, we frequently find identification problems regarding poorly detailed descriptions...
The genus Rhabdias Stiles & Hassal, 1905 includes about 83 species of nematodes parasitic in amphibians and reptiles worldwide. Herein, we describe glaurungi sp. nov. from the hylid frog Scinax gr. ruber (Laurenti, 1768) Gunma Ecological Park, Santa Bárbara municipality, state Pará, Brazil. This has six small lips, an inflated cuticle along entire body a cup-shaped buccal capsule with smooth internal surface its anterior part irregularly folded posterior apical view. From 17 valid recognized...
The genus Oswaldocruzia Travassos, 1917 includes approximately 90 species that are parasitic on amphibians and reptiles around the world, of which 43 occur in neotropical region. However, molecular data supporting taxonomic status most scarce, their phylogenetic relationships remain unknown. Using specimens four molineid taxa (Oswaldocruzia belenensis Santos, Giese, Maldonado Jr. Lanfredi, 2008; chabaudi Ben Slimane & Durette-Desset, 1996, chambrieri 1996 Kentropyxia hylae Feitosa, Furtado,...
Studies on the helminth parasites of South American freshwater turtles are rare and punctual. The parasitic fauna Kinosternon scorpioides’ nematodes from Brazil is restricted to only four species: Serpinema magathi, monospiculatus, pelliculatus Spiroxys figueiredoi. present work aimed report occurrence species Falcaustra sanjuanensis (Nematoda: Kathlaniidae), a parasite an anuran Argentina, in large intestine K. scorpioides Brazilian Amazon. specimens were collected, anesthetized,...
During a helminthological survey on freshwater turtles from the Brazilian Amazon, we collected fresh and well-preserved nematodes stomach of Podocnemis unifilis Troschel, 1848, that resembled Orientatractis leiperi . The morphology and morphometry specimens described herein fits those original description. We also observed important morphological characters not reported previously or properly described, are reported here for first time: structure excretory pore (surrounded by radial cuticle...
Nematodes of the family Molineidae are most frequent helminths reported infecting digestive tract South American amphibians. The molineid genus Kentropyxia Baker, 1982 includes only 2 nominal species parasitic nematodes: sauria and hylae Feitosa et al., 2015 both from eastern Amazon. We describe a new nematode parasitizing Boana boans, geographica, wavrini different locations in bakeri n. sp. has corona radiata composed unequal lappets, smooth cephalic vesicle, claviform esophagus,...
The monotypic genus Pneumoatractis Bursey, Reavill, and Greiner, 2009 was erected to allocate nematodes collected from the lungs of freshwater turtle Podocnemis unifilis Troschel. During a helminthological survey parasites turtles Tocantins Xingu rivers, Pará State, eastern Amazon, Brazil, we found parasitizing stomach large intestine Po. expansa Schweigger. We assigned them new species Pneumoatractis, which is described herein. gibbonsae n. sp. resembles podocnemis by morphology oral...
The genus Serpinema Yeh, 1960 allocates parasitic nematodes of freshwater turtles distributed across the Oriental, Neotropical, and Palearctic regions. Five 10 valid species occur in Neotropical region, three have been recorded parasitizing Kinosternon scorpioides Linnaeus, 1766. In present work, we describe a new Serpinema, gastrointestinal parasite K. from Brazilian Amazon, using light scanning electron microscopy. pelliculatus n. sp. differs other by number distribution caudal papillae...
Leptodactylus fuscus is a small-sized species widely distributed across South America. However, so far, no works have been addressed to analyze if biotic and abiotic factors may influence the parasite community in this species. Thus, present work aims describe composition structure of evaluate environmental correlated distribution for host. We collected 36 L. specimens from February 2018 January 2019. The hosts were necropsied, parasites identified. To test effect variables (temperature,...
During a helminthological survey of snakes in the Cerrado Biome Maranhão State, Brazil, we found intestinal nematodes
