Context

  • Researchers from Mizoram University’s zoology department have discovered a new species of coral snake in the state.
  • It has been named Sinomicrurus gorei after British India doctor Gore.

Details

  • This newly discovered coral snake species is locally recognised as "Rul Thi Hna" due to its striking resemblance to Thi Hna, a traditional amber necklace in the Mizo culture.
  • Until now, S Sinomicrurus gorei was commonly regarded as the same species as S macclellandi due to their close resemblance.
  • A recent investigation now supports the notion that it is indeed a distinct species, as indicated by its unique patterns, scales, DNA, and skull characteristic.

Coral Snakes

Scientific Classification:

  • Family: Elapidae
  • Subfamily: Elapinae
  • Genus: Micrurus and Micruroides
