New research identifies the Himalayan pangolin as a separate species, providing crucial insights for conservation and strengthening efforts to combat illegal wildlife trafficking.

A groundbreaking international study has confirmed that the Himalayan pangolin is a distinct species, resolving a long-standing taxonomic mystery and offering conservationists a powerful new tool to fight the illegal wildlife trade.

Published in the journal Communications Biology, the research identifies the Himalayan pangolin as Manis aurita, a species that inhabits Nepal, northern India, Bhutan, and parts of Myanmar. The discovery was made possible by combining modern genetic analysis with DNA extracted from a nearly 190-year-old museum specimen, demonstrating the critical role of natural history collections in modern conservation science.

Researchers say the finding will improve efforts to identify poached pangolin scales, guide species-specific conservation planning, and prevent the accidental release of the wrong species during reintroduction programs.

A Hidden Species Revealed

Pangolins are unique, medium-sized mammals found only in Asia and Africa. Covered in protective keratin scales, they are the world’s most heavily trafficked mammals due to the illegal demand for their scales and meat. All eight pangolin species face severe threats from poaching and habitat loss.

For decades, scientists believed that Chinese pangolins across East Asia and the Himalayan foothills belonged to the same species. However, recent genetic evidence suggested that pangolins living in the Himalayan region represented a separate evolutionary lineage.

The latest study confirms this distinction by identifying the Himalayan population as Manis aurita, an overlooked species first described in 1836 but later downgraded to a subspecies of the Chinese pangolin.

According to the researchers, recognizing the Himalayan pangolin as a distinct species is essential because effective conservation depends on accurately identifying the animals that require protection.

DNA from a 19th-Century Specimen Solves the Mystery

The breakthrough came through an unusual source—a museum specimen collected nearly two centuries ago.

Researchers extracted and sequenced DNA from the original Manis aurita type specimen preserved at the Natural History Museum in London. The specimen dates back to 1836, making it almost 190 years old.

The ancient DNA was then compared with genetic material collected from modern Himalayan pangolins.

The results confirmed that today’s Himalayan populations are genetically identical to the historical specimen, proving that the correct scientific name for the species is Manis aurita.

The finding also means that the name Manis indoburmanica, proposed by another research group in 2025 for the Himalayan population, is no longer valid under international scientific naming rules because the earlier name takes precedence.

The study highlights how museum collections continue to play a vital role in answering modern scientific questions, even centuries after specimens were first collected.

Small Physical Differences, Major Conservation Importance

Although the Himalayan pangolin closely resembles the Chinese pangolin, researchers identified several distinguishing characteristics.

Compared with the Chinese pangolin, Manis aurita has a larger body, a longer tail, and noticeably smaller ears. In fact, the species name aurita refers to its distinctive ears.

Equally important is the species’ geographic distribution.

The Himalayan pangolin occupies mountain foothills stretching across Nepal, northern India, Bhutan, and parts of Myanmar, while the Chinese pangolin occurs in different regions. Their ranges do not overlap.

Understanding these distribution boundaries is essential for conservation planning because each species faces unique ecological conditions and threats.

Strengthening the Fight Against Wildlife Trafficking

Scientists say one of the study’s most significant contributions lies in its application to wildlife crime investigations.

Pangolins are illegally hunted primarily for their scales, which are widely used in traditional medicine despite the lack of scientific evidence supporting their medicinal value. Their meat is also considered a luxury product in parts of Asia.

In illegal wildlife markets, authorities usually recover loose scales rather than entire animals, making it extremely difficult to determine which pangolin species has been poached.

The new genetic reference data generated by the study allows forensic scientists to identify the species from seized scales with far greater accuracy.

By tracing confiscated scales back to specific species and geographic regions, conservation agencies can identify poaching hotspots, strengthen enforcement, and target anti-trafficking operations more effectively.

Researchers say this information could significantly improve international efforts to dismantle illegal wildlife trade networks.

Better Conservation Through Accurate Species Identification

The discovery also has important implications for species recovery programs.

Until now, conservationists may have unknowingly treated Himalayan and Chinese pangolins as the same species. This created the possibility of releasing Chinese pangolins into areas where only Himalayan pangolins naturally occur.

Recognizing Manis aurita as a separate species will help ensure that future breeding, translocation, and reintroduction programs use the correct animals, preserving the genetic integrity of wild populations.

Accurate taxonomy also enables governments to develop species-specific conservation strategies based on the ecological requirements and distribution of each pangolin species.

Museum Collections Continue to Shape Modern Science

The researchers emphasize that the study would not have been possible without museum collections housing historical specimens from across the world.

Because pangolins are rare and highly elusive in the wild, obtaining fresh samples from across their range is extremely difficult. Museum specimens collected over centuries provide scientists with access to valuable genetic material that would otherwise be unavailable.

By combining historical collections with modern DNA sequencing techniques, researchers were able to reconstruct the evolutionary history of Asian pangolins with unprecedented accuracy.

As illegal wildlife trafficking continues to threaten pangolin populations, the confirmation of the Himalayan pangolin as a distinct species provides conservationists with stronger scientific evidence to protect one of the world’s most endangered mammals.

The discovery underscores the importance of taxonomy in biodiversity conservation, demonstrating that correctly identifying species is not merely an academic exercise but a critical step toward preventing extinction and improving the effectiveness of global wildlife protection efforts.
