Even though dorsal colouration is highly variable, Boavistaindividuals are usually lighter than Salones.   Distribution. BoavistaIsland and adjacent islets.  Conservation status.Not Evaluated. Threatened by ongoing touristic development on Boavistasuch as beach resorts, as the favourable habitat of this gecko is coastal areas with sand and dunes, and it seems avoiding urban and heavily-developed areas ( Vasconcelos 2013a). Other authors ( López-Jurado et al.1999) reported disappearance of this gecko in areas where the introduced house gecko  Hemidactylus angulatusoccurs. This exotic gecko is widespreading and now it also occurs, apart from anthropogenic habitats, in natural areas on Boavista, posing a threat to the endemic  Hemidactylus( Vasconcelos et al.2013). In addition, climate change may worsen the ongoing drought conditions in this island, negatively affecting Boavistaleaf-toed geckos ( Vasconcelos 2013a). 3042847305 NHMUK L.
