Trimeresurus is a genus of pit vipers found in Asia from the Indian Subcontinent throughout Southeast Asia, China, and the Pacific Islands. Currently 44 species are recognized.^[2] Common names include Asian palm pit vipers,^[3]Asian lanceheads, and green pit vipers.^[4]

Description

Most species in the genus Trimeresurus are relatively small, primarily arboreal species, with thin bodies and prehensile tails. Most Trimeresurus species are typically green in color, but some species also have yellow, black, orange, red, or gold markings.

Feeding

The diet of Trimeresurus species includes a variety of animals, including lizards, amphibians, birds, rodents, and other small mammals.

Reproduction

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. kaulbacki , and T. macrolepis are oviparous, laying eggs. Also, the reproductive biology of some Trimeresurus species is as yet unknown.

Venom

Trimeresurus venom varies in toxicity between species, but all are primarily hemotoxic and considered to be medically significant to humans.

Geographic range

Species in the genus Trimeresurus are found in Southeast Asia from India (including regions of the North Chotanagpur division of Jharkhand) to Southern China and Japan, and the Malay Archipelago to Timor.^[1]

Taxonomy

Additional species that may be recognized by other sources include:^[11]

T. barati Regenass & Kramer, 1981. Commonly called Barat's bamboo viper, found in Indonesia.
T. fucatus Vogel, David & Pauwels, 2004. Commonly called the Siamese peninsula pit viper and found in southern Thailand, Myanmar, Malaysia.

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,^[12]^[13]^[14] since these have been shown not to be closely related to other Trimeresurus in recent phylogenetic analyses.

In addition, Malhotra and Thorpe (2004)^[13] 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, salazar, strigatus, trigonocephalus, wiroti
Cryptelytrops	albolabris, andersonii, cantori, erythrurus, fasciatus, honsonensis (Hon Son Pit Viper), insularis, kanburiensis, labialis, macrops, purpureomaculatus, rubeus, 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,^[14]^[15] but not all^[11]^[16] 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.^[17]

Ovophis monticola, commonly known as the Chinese mountain pit viper, is a pit viper species found in Asia. Currently, two subspecies are recognized, including the nominate subspecies described here. Recent taxonomic work suggests that most of these should be considered as separate species. IUCN has already evaluated O. m. makazayazaya as Ovophis makazayazaya.

Protobothrops mangshanensis, commonly known as the Mangshan pit viper, Mangshan pit viper, Mt.

This is a nocturnal pit viper that is also known as the ''Mangshan iron-head snake'', ''Chinese pit viper'', and the ''Ironhead viper''. They eat frogs, birds, insects, and small mammals. They have a white tail tip that they wiggle to mimic a grub so that prey comes into striking range—a behaviour known as caudal luring. The venom causes blood clotting and corrodes muscle tissue and can be fatal to humans if not treated. Unusually for vipers, P. mangshanensis is oviparous with the female laying clutches of 13–21 eggs which she will guard until they hatch.
