The karyotypes of two cyprinid species Garra rufa and G. ghorensis (Cyprinidae), belonging to the inland ichthyofauna of Israel and Jordan, were studied. For both species, diploid numbers (2n) were represented by 50 chromosomes. The number of chromosome arms (NF) was relatively similar in both species and varied from 86 (76+10m) to 92 (80+12m), depending on the degree of condensation of chromosomes in metaphase plates. In both species, karyological examinations indicated some morphological differences between female and male karyotypes.
