New locality records for four rare species of vipers (Reptilia: Viperidae) in Turkey

Abstract

We report new localities and range extensions for four vipers from Turkey. The distribution of Montivipera wagneri is extended substantially southwards into Muş province, showing that this species is not endemic to the Aras valley as previously stated in the literature. Similarly, an unverified photograph of Montivipera albizona from Erzincan province, at its currently known eastern limit, was confirmed with new material, and its range is extended substantially southwards to the Anamos (Nur) Mountains in Hatay province. Smaller range extensions are reported for Vipera ammodytes transcaucasiana and V. darevskii.
