relatives (Cnemidophorus, Teius, Dicrodon, and Kentropyx) have 2n = 46-56 chromosomes, general absence of a distinct break between macroand microchromosomes, and a majority of large chromosomes acrocentric. Within the Ameiva group only Dicrodon and Teius have 2n above 52. Two microteiids, Anadia bitaeniata and Pholidobolus montium have 2n = 46 chromosomes with a marked break between 10 pairs of macrochromosomes and 13 pairs of microchromosomes; many of the macrochromosomes are two-armed.
