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.
