【 摘 要 】

Three new species of the genus Oswaldocruzia Travassos, 1917 belonging to the sub-family Molineinae are described from the stomach and/or the small intestine of Enyalius spp. from Brazil. They belong to group 6 of Ben Slimane, Chabaud & Durette- Desset (1996). In this group they share along with O. peruensis Ben Slimane, Verhaag & Durette-Desset, 1995, a parasite of Iguanidae from Peru the followings linked characters: (i) a caudal bursa of type II; (ii) cervical alae present; (iii) undulated cuticular ridges. The Peruvian species differs from the Brasilian species by the absence of a strut in the cervical alae, by a small number of cuticular ridges at mid-body and by a spicular fork with a ramified inner twig. Oswaldocruzia fredi n. sp., a parasite of the stomach and the small intestine of Enyalius iheringii, mainly differs from the two other species by the absence of the oesophageal ventral cuticular ridges. Oswaldocruzia benslimanei n. sp., a parasite of the small intestine of Enyalius bilineatus, differs from Oswaldocruzia burseyi n. sp., a parasite of the stomach of Enyalius perditus, by the division of the fork at 23.4 % of spicule length (versus 32 %), and the length of the blade longer than the fork. Oswaldocruzia subauricularis sensu Freitas, 1955 nec Rudolphi, 1819 and O. mazzai sensu Vicente, 1981 nec Travassos, 1935 should be considered as species inquirendae.
