The original genus Trimeresurus underwent substantial revision.


On behalf of molecular and morphological findings Malhotra and Thorpe 2004 split the genus Trimeresurus up into various new genera or reactivated ancient taxa. They proposed the genera Cryptelytrops, Himalayophis, Parias, Peltopelor, Popeia and Viridovipera.


David et al. (2011) proposed to adapt the findings of Malhotra and Thorpe but to define the new genera as 'clades'/subgenera.


See also Trimeresurus (Craspedocephalus) sp. for detailed discussion about the revision of the genus Trimeresurus.
