Chromosomal banding pattern in the Cyprus spiny mouse, Acomys nesiotes

The karyotype of a male Acomys nesiotes (Rodentia, Muridae) from Northern C yprus contained 38 chromosomes (NFa=66, NF=68). C-heterochromatin was local ized in centromeric areas of certain autosomes and the X chromosome. The G- banding pattern of chromosomal arms of A, nesiotes was very similar to that of A, cilicicus. The karyotypes of these two species differed because of a single autosomal Robertsonian rearrangement. A. nesiotes, A. cilicicus, an d A. cahirinus represent a group of karyotypically closely related species. In Eastern Mediterranean, the other group includes A. dimidiatus.
