Trimeresurus hageni, commonly known as Hagen's pit viper[4] and Hagen's green pit viper,[1] is a species of venomous snake in the subfamily Crotalinae of the family Viperidae. The species is native to Southeast Asia. There are no subspecies that are recognized as being valid.[5]

Etymology

[edit]

The specific name, hageni, is in honor of German naturalist Dr. Bernhard Hagen, who collected mammals, birds, reptiles, and insects in the eastern part of Sumatra.[6][7]

Scalation of T. hageni includes 21 rows of dorsal scales at midbody, 176–198 ventral scales, 63–89 subcaudal scales, and 9–12 supralabial scales.[4] The lectotype has a total length (including tail) of 97 cm (38 in).[3]

The type locality given is "Sumatra ... [and] island of Banka". Brongersma (1933) emended this to "Deli, Sumatra".[2]

The preferred natural habitat of T. hageni is forest, at altitudes of 100–300 m (330–980 ft).[1]
