Karyological studies of four agamid lizards from Semnane province of Iran

Iran possesses about ۲۴۱ species of reptiles, which ۵۵ species of them (۲۲.۸%) are endemic to Iran. Agamidae is the important family of reptile in Iran with ۲۲ species, which is poor in terms of chromosomal studies. In this paper, karyological survey was made for four species of the family Agamidae by bone marrow cell preparations. Karyotype of male and female of Laudakia caucasia (۲n=۳۴) was consisted of ۶ pairs macro and ۱۱pairs of microchromosomrs. Karyotype of Laudakia nupta nupta (۲n=۳۶) was including of ۶ pairs of macro and ۱۲ pairs of microchromosomes. Karyotype of Phrynocephalus scutellatus (۲n=۴۶) was consisted of ۲۲ macro and ۲۴ microchromosomes, which is reported here for the first time. Also, new cytotype of Traplus agilis agilis (۲n=۴۹) is reported here for the first time. Karyotype of this species was consisted of ۲۱ large acrocentric and ۲۸ microchromosomes, which one of the acrocentric chromosomes may be a sex chromosome.
