Protobothrops mangshanensis, commonly known as the Mangshan pit viper, Mangshan pitviper, Mt. Mang pitviper, or Mang Mountain pitviper, is a venomous pit viper species endemic to Hunan and Guangdong provinces in China. No subspecies are currently recognized. 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 kill people. Unusually for vipers, P. mangshanensis is oviparous with the female laying clutches of 13–21 eggs which she will guard until they hatch.

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.
