      Abstract

      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, 1951) Hugot, 1986 and the cestode R. (R.) trinitatae) represent new host record for Dasyprocta fuliginosa. New morphometric data and remarks about each species are provided.
