New occurrence of Sinovipera sichuanensis in Guizhou.

Three Asian green pit vipers were collected in August 2013 during a field trip in Fanjin Mt. National Conservation Area, Guizhou. These specimens were identified as Sinovipera sichuanensis, based on subsequent examination and comparison. This is a new record of the genus Sinovipera and S. sichuanensis in Guizhou, and the first time that male specimens have been collected in the field.
