In the scope of current study, 41 specimens of the subgenus Terricola
collected from nine different localities in Trabzon, Rize and Artvin provinces in
Eastern Black Sea Region were subjected to detailed morphological and
comparative biometric analyses. Based on those analyses; presence of two species,
Microtus (Terricola) subterraneus and Microtus (Terricola) majori were
determined in the region. Evaluation of the 12 specimens belonging to M. (T.)
subterraneus showed that there is no intrapopulational variation within this species.
Two different populations of M. (T.) majori were determined in the region studied,
based on morphological differentiations in enamel cusp patterns of 29 specimens.
Additionally, as a result of the evaluations made, it was determined that both species
could be found in the similar habitats throughout study area and therefore that these
two species can be coexist as sympatric within the same geographic area.
