Four samples of Vipera berus barani are recorded from Alaçam Village, Kestel/Bursa and Gölcüğez Village, Ünye/Ordu. The meristic and metric characteristics and the color-pattern features of the samples captured from additional localities are given in detail and compared with the specimens from other localities with regard to literature. A database of 30 distribution records of V. b. barani was provided and the climatic preference was analyzed. The average AUC value was 0.955 and the most effected bioclimatic variable of V. b. barani distribution range is precipitation of driest month (bio14) (55.2%). Under the distribution model, Black Sea borders of Turkey and southeast of Marmara Sea are seen more suitable places for the species.
