Ovophis Burger in Hoge & Romano-Hoge (type species: Trimeresurus monticola Günther 1864) |
Contents:
8 species, of which 2 (25.0%) are endemic.
Endemism: 0%  100%
Remarks:
Previously part of the genus
Trimeresurus.
Formerly included
Garthius chaseni.
The recently revealed presence of more than one species in parts of northeastern India, northwestern Burma, western China, and north and central Vietnam has
complicated interpretation of surveys done in the past (Malhotra, Dawson, Guo & Thorpe 2011).
The distributions given below should be regarded as tentative, since much confusion regarding the validity and distribution of the various taxa of the genus
continue to occur in the literature.
A revision of the genus is needed.
Distribution:
E. Asia, Malay Archipelago.

|
| |
Ovophis convictus Burger in Hoge & Romano-Hoge 1981 |
|
| |
Ovophis monticola convictus Golay & al. 1993 |
Remarks:
Previously regarded variously as either a subspecies of monticola (e.g., Golay & al. 1993) or as a separate species (e.g., Burger in Hoge & Romano-Hoge 1981; Das & Yaakob 2007; Das 2010). Validity confirmed by Malhotra, Dawson, Guo & Thorpe (2011). Records from southern Laos and southern Vietnam are provisionally assigned to convictus herein, although the status of these populations needs clarification (Malhotra, Dawson, Guo & Thorpe 2011).
Distribution:
Cambodia,
Indonesia
(Sumatra),
Laos,
Malaysia
(West Malaysia
[incl.

Trimeresurus gracilis Oshima |
|
| |
Ovophis gracilis Wallach, Williams & Boundy 2014 |
Remarks:
Status uncertain, but possibly related to Ovophis okinavensis (e.g., Malhotra & Thorpe 2000; Guo, Malhotra, Creer & Pook 2009; Malhotra, Creer, Pook & Thorpe 2009). Should be referred to a separate genus, according to Malhotra & Thorpe (2004). Hoser (2012) placed the species in the new genus Oxyus, a valid names, unless the publication becomes rejected (David & Vogel in Visser 2015). Since Hoser's publications are generally ignored herein as a rule, Wallach, Williams & Boundy (2014) are followed in placing gracilis in the genus Ovophis.
Distribution:
Taiwan.

Trimeresurus monticola meridionalis Bourret (David & Vogel 2012) |
|
| |
Ovophis monticola meridionalis Burger in Hoge & Romano-Hoge 1981 |
Other common names:
meridionalis: Southern Mountain Pitviper
monticola: Western Mountain Pitviper
Remarks:
Previously included convictus, makazayazaya, tonkinensis, and zayuensis.
Records from Chongqing, Gansu, Guangdong, Guangxi, Guizhou, Henan, Hunan, Jiangxi, Shaanxi, Sichuan, and Zhejiang are tentatively referred to makazayazaya.
Some older records from Bhutan (e.g., Wall 1907, Mahendra 1984) were based on Waddell (1899), which in fact referred to specimens from Sikkim
(Tillack, Shah, Gumprecht & Husain 2003), but several other authors have since then reported the species from the country.
Records from the Sunderbans in Bangladesh are doubtful and need confirmation, but the species is present in the Chittagong Hill tracts
(Gumprecht, Tillack, Orlov, Captain & Ryabov 2004).
Status of the taxon meridionalis is uncertain; it was previously regarded as a synonym of convictus (e.g., Golay & al. 1993; Zhao & Adler 1993).
Distribution:
Bhutan,
China
(Tibet,
Yunnan),
India
(Arunachal Pradesh,

Trimeresurus okinavensis Boulenger |
|
| |
Lachesis okinavensis Boulenger 1896 |
|
| |
Ovophis okinavensis Burger in Hoge & Romano-Hoge 1981 |
Remarks:
The systematic position of this species has been questioned (e.g., Malhotra & Thorpe 2000; Tu, Wang, Tsai, Toda, Lee, Zhang & Ota 2000).
A closer relationship with gracilis was suggested, but no taxonomic rearrangement has been made so far.
It is recommended to avoid using the common name "Okinawan Pitviper" to prevent confusion with the Okinawan Habu
(Protobothrops flavoviridis).
Distribution:
Japan
(Ryukyu Islands
[Okinawa Islands,
Satsunan Islands
(Amami Islands
[Tokunoshima],
Tokara Islands)]).

Remarks:
Regarded by some authors as a subspecies or a synonym of monticola (e.g., McDiarmid, Campbell & Touré 1999) or of its subspecies convictus (e.g., Orlov, Ananjeva & Khalikov 2002), but as a valid species by others (e.g., Golay & al. 1993; Malhotra, Dawson, Guo & Thorpe 2011).
