Different chromosomal races of the Nannospalax ehrenbergi (Nehring, 1898) complex inhabit south-eastern Turkey. In spite of the fairly restricted range of this mole rat in Turkey, no less than eight different karyotypes have been reported so far. These differ in diploid number (range from 52 to 58), fundamental number of chromosomal arms (ranging between 72 and 90) and in the fundamental number of autosomal arms (ranging from 68 to 86). The most common chromosomal form is 2n = 52, NF = 76, NFa = 72, which is known from Southeast Anatolia. In this paper I report on a new N. ehrenbergi karyotype from south-eastern Turkey. In 18 specimens investigated, the diploid number of chromosomes was 2n = 56, NF = 66, and NFa = 62. The karyotype consisted of 4 pairs of metacentrics/submetacentrics and 23 pairs of acrocentrics. The X chromosome was medium-sized submetacentric and the Y chromosome was small acrocentric. This chromosomal set is different to the most common Turkish N. ehrenbergi karyotype (2n = 52) and also differs markedly from the known chromosomal forms from Gaziantep (2n = 56, NF = 82, NFa = 78) and Tarsus (2n = 56, NF = 72, NFa = 68 ).
