Trimeresurus is a genus of venomous pitvipers found in Asia from Pakistan, through India, China, throughout Southeast Asia and the Pacific Islands. Currently 35 species are recognized.[2] Common names include Asian pit vipers,[3] Asian lanceheads and Asian lance-headed vipers.[4]

[edit] Description
Most are relatively small, primarily arboreal species, with thin bodies and prehensile tails. They are typically green in color, but some species also have yellow, black, orange or red markings.
[edit] Feeding
Their diet includes a variety of other animals, including rodents, lizards, amphibians and birds.
[edit] Reproduction
Like most viper species, they are ovoviviparous.
[edit] Venom
Their venom varies between species in toxicity, but all are primarily hemotoxic and considered to be medically significant to humans. Urban legends of a "Two step viper" have been created around this genus suggesting that a certain species has the toxicity to kill a person within seconds, a reasonable explanation however is that there is a possibility of major allergic reaction to toxins which might have been misconceived as a deadly new species' venom.
[edit] Geographic range
Southeast Asia from India to southern China and Japan, and the Malay Archipelago to Timor.[1]

The genus Trimeresurus sensu lato has been the subject of considerable taxonomic work since 2000, resulting in the recognition of additional genera within this complex. Most authors now recognise the genus Protobothrops for the species cornutus, flavoviridis, jerdonii, kaulbacki, mucrosquamatus, tokarensis, xiangchengensis,[8][9][10] since these have been shown not to be closely related to other Trimeresurus in recent phylogenetic analyses.
Malhotra and Thorpe (2004)[9] proposed a radical shake up of the entire genus, splitting Trimeresurus into seven genera. Their proposed arrangement (including species described since 2004) is shown in the table below:
| Genus | Species included |
|---|---|
| Trimeresurus | andalasensis, borneensis, brongersmai, gramineus, malabaricus, puniceus, strigatus, trigonocephalus, wiroti |
| Cryptelytrops | albolabris, andersonii, cantori, erythrurus, fasciatus, honsonensis (Hon Son Pit Viper), insularis, kanburiensis, labialis, macrops, purpureomaculatus, septentrionalis, venustus |
| Himalayophis | tibetanus |
| Parias | flavomaculatus, hageni, malcolmi, mcgregori, schultzei, sumatranus |
| Peltopelor | macrolepis |
| Popeia | barati, buniana, fucata, nebularis, popeiorum, sabahi |
| Viridovipera | gumprechti, medoensis, stejnegeri, truongsonensis, vogeli, yunnanensis |
This new arrangement has been followed by many,[10][11] but not all[12] subsequent authors.
