Trimeresurus andalasensis David, Vogel, Vijaykumar & Vidal, 2006 Craspedocephalus andalasensis,[2] commonly known as the Sumatran palm pit viper,[1] is a venomous pitviper species native to the Indonesian island of Sumatra.

Though known from a few specimens only, it is likely to be widespread in Sumatra.

[1] C. andalasensis occurs in wet montane forests at elevations of 500–1,130 m (1,640–3,710 ft) above sea level.

Although it is negatively impacted by deforestation, it is believed to be widespread enough to not be threatened overall.

C. andalasensis occurs in the Mount Leuser National Park.
