Trimeresurus puniceus is a venomous pitviper species endemic to Southeast Asia. No subspecies are currently recognized.[5]


Adults may attain a total length of 64 cm (25 in), which includes a prehensile tail 9 cm (3.5 in) long.[6]

Dorsally, T. puniceus is gray, brown, or red, with dark blotches or crossbars, which may merge to form an undulating stripe. On each side of the head, behind the eye, is a light streak. Ventrally, it is powdered with dark brown, and usually has lateral series of yellowish spots.[6]

Scalation includes 21-23 rows of dorsal scales at midbody, 158-173 ventral scales, 41-56 subcaudal scales, and 10-13 supralabial scales.[3] The dorsal scales are weekly keeled, and the anal plate is entire.[6]
