Gerbils of he Palaearctic are a relatively young group (known from the Pliocene) with around 145 species widespread in Africa, south Palaearctic, and south India. Comparative cytogenetic of many groups of species are style unknown. We studed G- and C- banded chromosomes of 7 species of the genus Meriones, namely M. tamariscinus, M. persicus, M. vinogradovi, M. libycus, M. unguiculatus, M. meridianus (including M. dahly), M. tristrami and one of the genus Rhombomys, R. opimus (284 animals from 35 local populations) from the former USSR. G-banding comparisons identified many fusion/fission rearrangements. We were able to allocate 15 homologous biarmed chromosomes to two or more species. A high degree of similarity was found between two species of Meriones: M. tamariscinus (2n=40, NF=78) and M. persicus (2n=42, NF=78) on the one hand and R. opimus (2n=40, NF=78) on the other hand. We suggest that M. tamariscinus is a sister taxon to Rhombomys and Meriones. The modes of chromosomal reorganizations between Meriones species are discussed.
