Studies focusing on communities of helminths from Brazilian lizards are increasing, but there are many blanks in the knowledge of parasitic fauna of wild fauna. This lack of knowledge hampers understanding of ecological and parasitological aspects of involved species. Moreover, the majority of research has focused on parasitic fauna of lizards from families Tropiduridae and Scincidae. Only a few studies have looked at lizards from the family Leiosauridae, including some species of Enyalius. This study presents data on the gastrointestinal parasite fauna of Enyalius perditus and their relationships with ecological aspects of hosts in a disturbed Atlantic rainforest area in the state of Minas Gerais, south-eastern Brazil. Two nematode species, Oswaldocruzia burseyi [(Molineidae) and Strongyluris oscari (Heterakidae) were found. Nematode species showed an aggregated distribution in this host population, with O. burseyi being more aggregated than S. oscari. The present study extends the range of occurrence of O. burseyi to the Brazilian continental area. © 2011 Cambridge University Press.

Tropiduridae (Squamata: Iguania) is a lizard taxon widely distributed in the neotropics. Among its representatives, some species are classified as generalists regarding habitat usage. Others exhibit a very restricted and probably relict distribution, and are strongly associated with predominantly sandy and dry habitats. Within this rather ecologically similar than phylogenetically closely related group we examined specimens of Eurolophosaurus amathites, E. divaricatus, Tropidurus hygomi, T. psammonastes for endoparasites. In all four species examined we recorded parasitic nematodes (Nemathelminthes: Nematoda). At least three nematode species were recovered: Parapharyngodon sp., Physaloptera lutzi and Strongyluris oscari, with Ph. lutzi being the most abundant parasite encountered in all lizard species examined. In spite of the hosts' habitat specialization, these parasites are also found frequently in non-psammophilous tropidurid species as well as in other squamates. Individual species richness per lizard was low, with usually just one species parasitizing at a time. These are the first parasites registered for these tropidurids and constitute a total of six new host records.

Contribuição ao conhecimento de espécies venezuelanas do gênero Lespesia Robineau-Desvoidy (Diptera, Tachinidae), com descrições de novas espécies. Foi realizado um estudo taxonômico de espécies venezuelanas do gênero Lespesia Robineau-Desvoidy, 1863 (Diptera, Tachinidae), baseado na coleção do "Museo del Instituto de Zoología Agrícola Francisco Fernández Yépez (MIZA) de la Universidad Central de Venezuela - Maracay". Seis espécies foram reconhecidas, dentre estas duas são descritas como novas, Lespesia giovannae sp. nov. e Lespesia oscari sp. nov., e três são registradas pela primeira vez para a Venezuela: Lespesia affinis (Townsend, 1927), Lespesia protoginoi (Blanchard, 1966) e Lespesia spitzi Guimarães, 1983. São apresentadas redescrições e chaves para as espécies.
