For more than 160 years, the Himalayan pit viper was treated as one wide-ranging snake across Pakistan, India, and Nepal. Now, a new study reveals a much more complex reality: five separate species, including three that science<\/a> had never formally recognized.<\/p>\n\n\n\n

The discovery is not just a neat naming update for snake experts. It changes how researchers understand biodiversity in one of Asia\u2019s least explored mountain regions<\/a>, and it raises a sharper conservation question. What happens when one \u201ccommon\u201d snake turns out to be several highly local animals, each living in a narrow mountain pocket?<\/p>\n\n\n\n

A snake with five names<\/h2>\n\n\n\n

The original Himalayan pit viper, Gloydius himalayanus<\/em>, was first described in 1864. Under the new revision, that species is more tightly limited to northwestern India, usually at elevations of about 3,300 to 11,500 feet.<\/p>\n\n\n\n

The Chamba pit viper<\/a>, Gloydius chambensis<\/em>, had already been described in 2022 in India\u2019s Chamba district. The new work expands its known range westward into the Kashmir Valley, at about 1,300 to 8,200 feet.<\/p>\n\n\n\n

Then come the three newcomers. The Hazara pit viper, Gloydius hazarensis<\/em>, was identified in northeastern Pakistan. The Hindu Kush pit viper, Gloydius hindukushensis<\/em>, lives in the eastern foothills of the Hindu Kush in northwestern Pakistan. The Nepali pit viper, Gloydius nepalensis<\/em>, is now known from western and central-western Nepal.<\/p>\n\n\n\n

Why museum DNA mattered<\/h2>\n\n\n\n

This was not a simple case of spotting a strange snake in the wild and giving it a new name. The researchers combined modern fieldwork with historical museum specimens, fresh and old DNA, body structure, skeletal anatomy, distribution data, and ecological evidence.<\/p>\n\n\n\n

That mix matters. Some of the crucial evidence had been sitting in collections for decades, even more than a century, before new genetic tools made it useful again. \u201cMuseum specimens are not just records of the past,\u201d said Sylvia Hofmann of Museum Koenig<\/a>.<\/p>\n\n\n\n

In practical terms, the museum shelf became a time machine. A preserved snake collected long ago could help scientists decide what the \u201creal\u201d Himalayan pit viper is, and what had been mistakenly grouped under the same name.<\/p>\n\n\n\n

Mountains made the split<\/h2>\n\n\n\n

The Himalaya and Hindu Kush are not smooth landscapes. They are broken by steep ridges, deep valleys, cold slopes, and river systems that can keep animals apart for very long periods.<\/p>\n\n\n\n

The study points to major river valleys, including the Indus and Karnali, as possible historical barriers that helped separate these snake populations. Over time, that isolation appears to have allowed distinct lineages to form.<\/p>\n\n\n\n

Anita Malhotra<\/a>, a pit viper specialist at Bangor University who was not involved in the work, told Mongabay that the finding was not surprising because the snakes were likely separated by the \u201cextreme topography of the mountains.\u201d She also warned that small ranges can make them \u201cextremely vulnerable to climate change<\/a>.\u201d<\/p>\n\n\n\n
