Morne Dubois Least Gecko

Sphaerodactylus nycteropus


Little is known about Morne Dubois least gecko as it has not been recorded since it was described in 2009 despite subsequent surveys.

Morne Dubois least gecko is part of the family Sphaerodactylidae which diverged from all other families of reptiles 87 million years ago, around the time that humans and rabbits shared a common ancestor!

This West Indies species is threatened by habitat loss due to wood harvesting and charcoal production, and agricultural expansion. Morne Dubois least gecko does not occur in any protected area and further research is required to determine the distribution and population trends.

  • Order: Squamata
