Cnemidophorus

Distribution and habitat. Cnemidophorus sp. 3 is endemic to Brazilian Amazonia, in Pará state, and until now known only from one enclave of open vegetation between the lower Trombetas and Nhamundá rivers, near Sapucuá Lake (Fig. 6). It is sexually dimorphic, terrestrial, and diurnal, and can found on open sandy soil, among grasses and under bushes (MAR-J field data). Even though Cnemidophorus sp. 3, C. lemniscatus, and C. cryptus are found in areas relatively close, they were not recorded in the same enclaves of open vegetation.
