Abstract
In this study, one death Platyceps najadum was found on road in Aşağıyanlar Village/Çankırı in Northern Turkey. The distribution range of the species has been extended 88 km from known localities. The specimen was evaluated in terms of morphology and colour-pattern characteristics. The climatic preference of P. najadum was analyzed. The average AUC value was 0.771 and the most effected bioclimatic variable of P. najadum distribution range is precipitation of wettest month (bio13) (47.5%). Under the distribution model, coast of Aegea, Northern Black Sea and Mediterranean is seen more suitable places for the species.
