In News: A new species of dwarf boa has been discovered in the upper Amazon basin, reported a paper published in the journal European Journal of Taxonomy.

Dwarf Boa:

  • The snake from the Tropidophiidae family was found in the cloud forest in northeastern Ecuador and was up to 20 centimetres long.
  • Tropidophis cacuangoae can be identified from other reptiles in the same genus based on its external features and bone structure.
  • Its colouring is primarily light brown with darker brown or black blotches — similar to a boa constrictor.
  • The species inhabits eastern tropical piedmont and lower evergreen montane forests in the Amazon tropical rainforest biome
  • It is suspected to be an Ecuadorian endemic.
  • Both specimens were found within 50 kilometres of each other — Colonso Chalupas national reserve and in the private Sumak Kawsay park.
  • The species is unusual for having a “vestigial pelvis”, which is characteristic of primitive snakes.
  • This could be evidence that snakes descended from lizards that lost their limbs over millions of years.
  • The snake’s name honours Dolores Cacuango, an early 20th-century pioneer in the fight for indigenous and farmers’ rights in Ecuador.
  • The discovery of T cacuangoae demonstrates that small and cryptic vertebrates can undergo large periods of time without being detected.
  • The discovery of this new species highlights a critical need to accelerate research in remote areas where information gaps remain but are suspected of harbouring high biodiversity and are severely threatened by human impacts
