Gloydius halys mogoi, or the Siberian Pitviper, is a subspecies of Halys pitviper from Mongolia and Siberia. As with all pit vipers, it is venomous.
Taxonomy The status of Gloydius halys mogoi is controversial, with some researchers believing it should be a junior synonym of G. h. halys, while others believe it is a full subspecies.Orlov, N.L. and Barabanov, A.V., 1999.
