Abstract A total of 651 iguanid and teiid lizards collected from Estados Portuguesa, Cojedes, and Guarico were found parasitized by eight Plasmodium species, one of which was undescribed. Plasmodium t. tropiduri Aragao & Neiva, 1909 parasitized Tropidurus hispidus , and P. colombiense Ayala & Spain, 1976 was found in Anolis auratus. Iguana iguana was host to P. rhadinurum Thompson & Huff, 1944 and to a new species characterized by schizonts with 6–25 nuclei, heavily pigmented when in erythrocytes. The round to oval, prominently pigmented gametocytes, which exceed the host cell nucleus in size, are more commonly found in proerythrocytes than in mature cells. Three Plasmodium species parasitized Ameiva ameiva: P. cnemidophori Carini, 1941; P. attenuatum Telford, 1973; and P. telfordi (Lainson, Landau & Shaw, 1971), the last species occurring both in pigmented and unpigmented forms. A detailed description is provided for P. minasense tegui Telford, 1979, a parasite of Tupinambis teguixin .
