Abstract :Karyological, morphological, bacular and phallic aspects of Prometheomys schaposchnikowi were examined based on 22specimens collected in Ardanuç and Ardahan. The diploid number of chromosomes is 2n=56, the number of autosomal arms isNFa=100, and the fundamental number is NF=104, the X chromosome is a large submetacentric, and the Y chromosome is thesmallest metacentric. In adults, sagittal crest begins in frontal region, ends in parietal region into two parts. The phallus is covered with spines. The length of phallus is 15.94 mm in average. The median part of distal baculum is 1.51 in length. Proximal baculum is 3.74 mm in length.
