Abstract: The morphological structure of seven chromosomal forms of Spalax leucodon was studied using numerical taxonomical methods. Fifty-five skull and external characters were used in multivariate analysis. The diploid number of chromosome is diverse even in adjacent localities. Discriminant Function Analysis (DFA) revealed the presence of three distinct groups for both males and females. DFA separated the three chromosomal forms (2n = 60, 50 and 56 NW) from each other. S. l. cilicicus has 2n = 60, 56 SW, 54, 52, 40 chromosomal forms; S. l. turcicus contains 2n = 56 NW; and S. l. nehringi includes 2n = 50 chromosomal form. M2 and M3 have 2 alveoli cubicles in chromosomal forms of 2n = 40, 50, 54, 56 NW, 56 S, while M2, 3 have 1 cubicles in chromosomal forms of 2n = 60 and 52.
