A new population and subspecies of the critically endangered Anatolian meadow viper Vipera anatolica Eiselt and Baran, 1970 in eastern Antalya province

We report on a new population of Vipera anatolica from the Geyik Mountain Range in eastern Antalya Province, Turkey. It represents only the second known location, and is situated in a valley about 200 km east from the terra typica at Kohu Dag in western Antalya Province. We compare both populations and, based on marked differences in morphology, habitat, genetics, and its geographically isolated location, we describe the recently discovered population as a new subspecies. Aspects of ecology, threats, and conservation needs are discussed.
