3.4. The baculum characteristics of Nannospalax ehrenbergi (Nehring, 1898)

A total of 7 bacula were examined from N. ehrenbergi . This species had the samples with the smallest bacula (5.03 mm), excluding N. labaumei . All of the bacula were curved dorsoventrally, and the most curved baculum was observed in this species (130.5°). The general structure of the baculum was slender. The baculum became thinner from the distal end to the proximal end. Therefore, the narrowest region occurred proximally. There was no variation in the shape of the baculum proximally, and this portion terminated evenly. Unlike in other species, the distal end of the baculum was convex or concave, with no incisions or openings. Distally, the baculum in this species was the narrowest of all of the species (0.42 mm). The baculum was cylindrical and the diameter decreased from the distal end to the proximal end, unlike in the other species. Laterally, the baculum was approximately circular
