Abstract
Chromosome complements of the following species were described: Agama sanguinolenta Pallas, 1813; A. caucasica Eichwald, 1813; A. erythrogastra Nikolsky, 1896; A. lehmanni Nikolsky, 1896; and A. hymalayana Steindachner, 1867. Agama sanguinolenta has 46 chromosomes, all of them being telocentric. The remaining 4 species show 2-n equal to 36:6 pairs of meta- or submetacentric macrochromosomes and 24 microchromosomes. Sex chromosomes have not been found. Possilbe evolutionary interpretation of a profound karyologic divergence in the genus Agama and karyotypic relationships of Agamidae with Iguanidae of the New World, are discussed.
