| A new species of Ophidascaris Baylis, 1920 is described on the basis of specimens recovered from the pit viper Bothrops jararaca Wied, 1824 in Brazil. The new species referred here was compared to other of the genus that are the closest. The differentiation was based on reliable morphological characters, mainly on what refers to the spicular length, number and distribution of caudal papillae, location of the vulvar opening, eggs size and aspect of the labial indentations. Moreover, female specimens are the only to possess a most prominent and characteristic post-anal tubercle-like structure and when analyzed together with the males, that show a great number of pre-cloacal papillae, the presence of an unpaired papilla and also of a less conspicuous... |

| The digenetic trematode Psilochasmus oxyurus (Creplin, 1835) Lühe, 1909, although with a large geographical distribution, is referred in geese (Anser anser Linnaeus, 1758) for the first time in South America, on the basis of specimens parasitizing Brazilian domestic geese, with a prevalence of 20%. Brief morphometric data on the parasites are included. Clinical signs, gross and microscopic lesions were not observed in the birds. |

| Four nematodes and one cestode species from three Brazilian agoutis - two Dasyprocta fuliginosa Wagler, 1832 and one Dasyprocta leporina (Linnaeus, 1758) - and six pacas - Agouti paca (Linnaeus, 1766) - captured in tributaries rivers in the middle and high Rio Negro microregion, State of Amazonas, Brazil, were studied. The nematodes Physaloptera torresi (Travassos, 1920) Ortlepp, 1922, Physocephalus mediospiralis (Molin, 1859) Hall, 1916 and the cestode Raillietina (R.) trinitatae (Cameron & Reesal, 1951) Baer & Sandars, 1956 are reported from the State of Amazonas for the first time. The studied helminths (the nematodes P. torresi, P. mediospiralis, Trichuris gracilis (Rud., 1819) Hall, 1916, Helminthoxys urichi (Cameron & Reesal,... |

| Two new tichostrongylid nematodes of the family Viannaiidae Durette-Desset & Chabaud, 1981 coparasites in Dasyprocta fuliginosa Wagler, 1832 from the State of Amazonas, Brazil, are described: Viannella trichospicula sp. nov. is differentiated from the other species of the genus by the extreme slenderness of its spicules. Avellaria intermedia sp. nov. is distinguished from the single type species Avellaria avellari Freitas & Lent, 1934, by a smaller number of cuticular ridges (17 versus 27), a higher ratio of spicule length/ body length (8% versus 5.6%) and spicules with a single tip. This genus, synonymized with the genus Viannella Travassos, 1918, by Durette-Desset (1968) is re-established, the female being didelphic. It is the first... |
