1 The number of genera in the lineage for which karyotypic data exist.

2 The number of genera in the lineage containing one or more species with a karytoype deviating from the 12+24 or 12+22 pattern.

3 Stenocercus, Tropidurus, Leiocephalus, and Liolaemus, each with 20 or more species, are treated as large genera.
