Abstract
In the context of an ecological study of lizard assemblages in the Dry Chaco, a lizard sampling was made in Chancaní, province of Córdoba (central Argentina) (31º20'14" S, 65º20'24" W). A hundred drift-fence pitfall traps were set in native forest areas with different degrees of degradation by fire, grazing and logging. Out of a sample of 171 individuals of Tropidurus etheridgei, I found one juvenile bearing polydactyly. This animal (SVL = 28 mm) had one extra digit in each forelimb and two extra digits in each hindlimb.
