- Common names: Christmas Island blind snake.
This species is classified as Vulnerable (VU) on the IUCN Red List with the following criteria: D2 (v2.3, 1994). This means that it is not Critically Endangered or Endangered, but is facing a high risk of extinction in the wild in the medium-term future. This is because the population is very small and characterized by an acute restriction in its area of occupancy. It is therefore prone to the effects of human activities (or stochastic events, the impact of which is increased by human activities) within a very short period of time in an unforeseeable future. Therefore, it is possible that this species may become Critically Endangered or even Extinct within a very short period of time. Year assessed: 1996.
