Overview

Sphaerodactylus williamsi, also known commonly as Williams's least gecko or the Haitian striped geckolet, is a small species of lizard in the family Sphaerodactylidae. The species is endemic to Haiti.

Sphaerodactylus williamsi faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in the Dominican Republic. The species' extremely small population size and restricted distribution make it highly vulnerable to stochastic events and further habitat fragmentation. Invasive species introduction and potential climate change impacts on its specialized microhabitat requirements pose additional risks to this critically endangered gecko.

Threat summary

Habitat

This species inhabits dry forests and scrubland areas in the Dominican Republic, typically found in leaf litter and under rocks or logs in areas with specific microclimate conditions. It requires well-preserved native vegetation with adequate ground cover and moisture retention for foraging and shelter.
