Trimeresurus is a genus of venomous pitvipers found in Asia from the Indian Subcontinent throughout Southeast Asia, China 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]

Description[edit]

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. Sometimes gold.

Feeding[edit]

Their diet includes a variety of other animals, including rodents, lizards, amphibians and birds.

Reproduction[edit]

Like most viper species, many of the species in the genus Trimeresurus are ovoviviparous, bearing live young. However, some species such as T. flavoviridis, T. gramineus, T. kaulbacki, and T. macrolepis are oviparous, lay eggs. Also, the reproductive biology of some Trimeresurus species is as yet unknown.

Venom[edit]

Their venom varies in toxicity between species, but all are primarily hemotoxic and considered to be medically significant to humans. One nickname for this snake among locals is "100 pace snake" in reference to the legend that, once bitten, a person can walk 100 more steps before dropping dead.

Geographic range[edit]

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.

In addition, 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.

David et al. (2011) considered some of the genera of Malhotra & Thorpe to be subgenera of the genus Trimeresurus, creating new combinations such as "Trimeresurus (Parias) flavomaculatus", "Trimeresurus (Popeia) popeiorum", "Trimeresurus (Viridovipera) stejnegeri", etc.[13]
