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

We report new localities and range extensi ons for four vipers from Turkey. The dis- tribution of Montivipera wagneri is extended substantially southwards into Mu ş province, showing that this sp ecies is not endemic to the Aras valley as previously stated in the literatu re. 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 substa ntially southwards to the Anamos (Nur) Mountains in Hatay province. Smaller range extensions are reported for Vipera am- modytes transcaucasiana and V. darevskii.
