The find, for the first time in the state of São Paulo - Brasil, a parasite, the Plasmodium (S.) tropiduri in lizards of genus Tropidurus is described. Initially it was related this parasite found, by other authors, in another areas of the Brasil and Venezuela. As far as the parasitology itself is concerned, the low parasite density encountered and the simular morfology as it was studied by Aragão et Neiva are reported. There remain the difficulties encountered in the discovery of exoeritrocitic forms in trombocytes. In entomological research, finding in low density, of the A. (N.) evansae and the A. (N.) argyritarsis is reported.
