Sixteen specimen of Microtus (Terricola) collected in subalpine meadows of the Pindos and Iti mountains were karyotyped. All 11 animals from the Pindos mountain had the same karyotype with 2n = 42, NF = 42. The individuals collected on Iti mountain had a karyotype with 2n = 40, NF = 42 characterized by a large pair of metacentric chromosomes. The two karyotypes were closely related and one might have derived from the other by a Robertsonian centric fusion/fission. In both karyo­types the X and Y chromosomes were large acrocentrics. The karyotypes of the voles studied were more similar to that described for M. (T.) thomasi than to the other species of Terricola known in Greece.
