Researchers have discovered a new species of non-venomous burrowing snake in Arunachal Pradesh, named Trachischium apteii.

Trachischium apteii

  • It was found under fallen logs inside a thickly forested area of the Tally Valley Wildlife Sanctuary near the town of Ziro in Arunachal Pradesh during a field expedition by researchers in July 2019.
  • It belongs to a group of fossorial snakes that live mostly underground, and surface mainly during or after a heavy monsoon shower.
  • Due to the burrowing habits of species of this genus, snakes belonging to the group are seldom seen and hence remain poorly studied.
  • This could have been one of the reasons that the species had eluded the researchers.

Physical features

  • Morphologically, the snake is distinguished by smooth and dorsal scales arranged in 15 rows throughout the body.
  • The dorsal colour of the holotype is dark brown to black with faint dorsal longitudinal lines.
  • Large-sized members of the genus measure about 293 mm to 299 mm (measuring less than a foot, that is 300 mm or 30 cm).

Behind the name

  • Trachischium apteii was named so to honour the contribution of Deepak Apte, well-known marine biologist and Director of the BNHS.
  • Trachischium species are commonly called slender snakes, and are currently known by seven species that are distributed across the Himalayas, and the Indo-Burma and Indo-China regions.
