DistributionRead full entry
Range DescriptionThis species is known from both of the islands of Western Samoa, as well as from four small islands northeast and northwest of the Samoa group. These four islands are Swains and Nukunono Islands of the Tokelau group (American Samoa), Pukapuka Island of the Danger group (Cook Islands), and Funafuti Island of Tuavalu (Gill 1993). This species is also known to occur in Wallis and Futuna (Adler et al. 1995).
The area in which this species is distributed is approximately 3,071 km². This has been calculated by taking the sum of the areas of each of the islands it inhabits. Its distribution is considered to be severely fragmented (C. Austin pers. comm. 2010).
