Abstract Specimens of the four most abundant diurnal lizards (Tropidurus torquatus, Cnemidophorus littoralis, Mabuya macrorhyncha and M. agilis) inhabiting the restinga of Jurubatiba, Rio de Janeiro state, Brazil were examined for nematodes. Eight species of nematodes were found. Tropidurus torquatus had the richest (8 species) and most diverse nematode fauna, whereas that of C. littoralis was the poorest (2 species) and less diverse. Tropidurus torquatus also had the highest overall prevalence (92%) and mean infection intensity (37.2; standard deviation 82.0; range 2-549). Similarities in nematode faunal composition between host species was generally low, except between the two Mabuya species.
