Molar Patterns in Microtus guentheri (Danford and Alston, 1880) (Mammalia: Rodentia) from Kırıkkale Province

Microtus guentheri is one of the most widespread rodent in Turkey. Morphotypes of upper and lower molar of 89 young and adult Guenther's voles, collected from central Anatolia have been examined and compared with the previous data given from Turkey. M2 of the young and adult specimens were non-agrestis morphotype. Young specimens possessed normal, duplicate and complex M3, whereas adult specimens possessed simplex form in addition to those forms. The complex form of M3 was determined from Central Anatolia with this study for the first time. Duplicate form of M3, was encountered more than the normal form in adult specimens. M1 of the young and adult specimens were found to be of arhombomorph type
