The chromosomal banding analysis of the karyotypes of Turkish populations of Eptesicus serotinus, Nyctalus lasiopterus and Barbastellus barbastellus was performed with the use of C-banding and Ag-NOR staining. The results obtained in E. serotinus and N. lasiopterus were congruent with previous data reported from other regions. The karyotype of E. serotinus (2n = 50, NF = 52) contained a moderate amount of centromeric C-heterochromatin and a single NOR was localized in an acrocentric autosomal pairs. The karyotype of N. lasiopterus (2n = 42, NF = 54) contained a higher amount of centromeric C-heterochromatin and the NORs were localized in two autosomal pairs. The karyotype of B. barbastellus was standard in its general characteristics (2n = 32, NF = 54, low amount of C-heterochromatin) but the NOR was localized in only one acrocentric autosomal pair. In studies from other regions, the NORs were recognized in all five acrocentric autosomal pairs of the complement of B. barbastellus.
