The Crotalinae, commonly known as pit vipers, or pit adders, are a subfamily of vipers found in Asia and the Americas. Like all other vipers, they are venomous. They are distinguished by the presence of a heat-sensing pit organ located between the eye and the nostril on both sides of the head. Currently, 23 genera and 155 species are recognized: These are also the only viperids found in the Americas. The groups of snakes represented here include rattlesnakes, lanceheads, and Asian pit vipers. The type genus for this subfamily is Crotalus, of which the type species is the timber rattlesnake, C. horridus.

It is listed as Least Concern in the IUCN Red List, on account of its widespread range in the Tibetan Plateau's steppes and semi-deserts.
Gloydius himalayanus also known as the Himalayan pit viper or the Himalayan viper is a venomous pitviper species found along the southern slopes of the Himalayas in Pakistan, India and Nepal. No subspecies are currently recognized. Himalayan pit vipers have been found up to 4900m above sea level, which makes it the highest living snake ever found.

Gloydius strauchi is a species of venomous pit viper in the subfamily Crotalinae of the family Viperidae. The species is native to western China. It is a small snake with a pattern of four longitudinal stripes, although some older specimens may be a uniform black. G. strauchi may be distinguished from G. monticola by its higher midbody dorsal scale count. This species jointly holds the altitude record for pitvipers together with Crotalus triseriatus of Mexico, both being found even above the tree line at over 4,000 m (13,000 ft). No subspecies were recognized as being valid, until a recent publication re-evaluated the taxonomic statuses of populations of G. strauchi and described the eastern Tibetan populations as a new species.
Maqu County is a county of the Gannan Tibetan Autonomous Prefecture in the south of Gansu province of China, bordering the provinces of Sichuan to the east and southeast, and Qinghai to the southwest, west and northwest. Its postal code is 747300, and in 1999 its population was 36,213 people. The word "Maqu" derived from the Tibetan name of Yellow River. The area of Maqu County is 10,191 km2 with an average altitude of 3,700 meters.

Gloydius lateralis is a species of venomous pit viper found in the Zharu Valley of Jiuzhaigou County, China. The species is active during sunny days in hot and dry areas along roadsides. The Zharu Valley is the sole known location of G. lateralis. This snake is assumed to eat small mammals like mice, based on the fur remnants found within its droppings. This species lineage is a sister taxon to G. swild, being morphologically and phylogenetically similar.
