The endemic Balkan vole taxon Microtus (Terricola) thomasi (Barrett-Hamilton, 1903) exhibits great karyological variability in Greece. In this study, populations belonging to two different karyotypic forms ('atticus' and 'thomasi') are examined both morphometrically and electrophoretically. A total of 140 individuals of M. (T.) thomasi were collected from 6 localities of south and central Greece. For the morphometric analysis, 27 variables (external body and cranial characters) were examined and evaluated according to multivariate analyses (PCA, MANOVA, CVA and CLUS). For the electrophoretic analysis, 18 putative genetic loci were examined and the allozymic data were treated by the biostatistical package BIOSYS-1. According to the results obtained, all the populations studied show little overall morphometric variability, whereas they are characterized by high electrophoretic variability. The populations studied are not grouped according to the karyotypic form. In almost all the cases, in the two UPGMA-dendrograms plotted according to morphometric and electrophoretic distances (Mahalanobis' and Nei's distances, respectively), the populations branching together belong to different karyotypic forms. Conclusively, the morphometric and electrophoretic results of this study revealed that the two karyotypic forms should not be considered separate species or subspecies, as it has been proposed by some authors in the past, and the populations studied can be considered only as different local populations of the rather variable vole species M. (T.) thomasi.
