New Snake Species Discovered in Mizoram

Summary of Findings on New Snake Species in Mizoram

• New Species Description: A new snake species, Trachischium lalremsangai, has been identified in the jungles of Mizoram, India, and Myanmar, highlighting biodiversity in the region.

• Researchers: The species was described by a team from Mizoram University and the Max Planck Institute for Biology, including:

  • Virender K. Bhardwaj
  • Amit K. Bal
  • Chhangte L. Tluanga (Mizoram University)
  • Zeeshan A. Mirza (Max Planck Institute)

• Naming: The species is named in honor of Professor Hmar Tlawmte Lalremsanga for his significant contributions to herpetology in India.

• Geographical Significance:

  • The Indo-Burma biodiversity hotspot measures 2.4 million square kilometers, encompassing northeastern India, parts of Bangladesh, Myanmar, and extending to Southeast Asia (e.g., Thailand, Vietnam).

• Discovery Context:

  • The first specimen was found in Murlen National Park (100 sq. km area) near the India-Myanmar border.
  • The second specimen was identified during a research visit to the California Academy of Sciences in September 2025, initially collected in Haka Township, Myanmar in 2007.

• Identifying Features:

  • Trachischium lalremsangai features two scales behind the eye and a light-brown belly, contrasting with related species, which have darker bellies.
  • It primarily feeds on earthworms and is defined as a "slender snake" that prefers underground living conditions.

• Ecological Importance:

  • The new species represents the 11th species within the Trachischium genus documented across Northeast India and the Himalayas, emphasizing the richness of the region's herpetofauna.

• Research Techniques: DNA sequences were analyzed to confirm the distinctiveness of the new species, underscoring advancements in genetic methods in wildlife research.

Implications:

This discovery represents an important addition to the biodiversity catalog of the Indian subcontinent and may provide insights into the ecological roles of subterranean reptiles in their ecosystems. Further study may reveal more about their biology and conservation needs in light of habitat changes within the Indo-Burma hotspot.
