Principal component and discriminat analyses failed to separate morphologically <em>M. dinellii</em> from <em>M. levis</em>. Also, mitochondrial sequences of the cytochrome <em>b</em> gene showed very low divergence, and the taxa did not form reciprocally monophyletic groups. Therefore, morphological and genetic analyzes provides a strong support to the conspecificity between <em>M. dinellii</em> and <em>M. levis</em>. This hypothesis is also supported by our direct examination of some topotypes of <em>M. dinelli</em> and color photograph of the syntype of <em>M. levis</em>.

The limits of variation of five <em>Apodemus</em> species (<em>A. flavicollis, A. witherbyi, A. sylvaticus, A. uralensis, A. mystacinus</em>) distributed in Turkey were determined. These species, which live in similar habitats and thus have a complex taxonomic situation, were genetically identified to determine location-specific variations and standard characters. It was determined whether geographical barriers such as the Marmara Sea, Istanbul and Çanakkale straits, Melet River and Çoruh River separate the populations of the species from each other. These inferences were discussed in terms of paleogeographic reasons. The Kızılırmak River or ecological constriction were found to separate <em>A. mystacinus</em> to west and east parts. Also, the İstanbul strait was found to cause a possible separation of <em>A. flavicollis</em> specimens. The Melet River and the Çoruh River were not found to cause a distinction within the species. Differences between island populations and mainland populations were determined in <em>Apodemus slyvaticus</em> and <em>A. witherbyi</em> distributed in the islands.
