DistributionRead full entry
Range DescriptionThis species is known from three islands (the two main islands Savai'i and Upolu, and the smaller island Nu'ulua) in Samoa, as well as from three small islands northeast and northwest of the Samoa group, and one to the southwest (Niuafo'ou in Tonga - Gill et al. 1994). The northern islands are Swain's Island (administered by American Samoa) and Nukunono in the Tokelau group (New Zealand) and Funafuti Island (Tuvalu - Gilll 1993). No recent records exist from Tuvalu, or from Tonga more recent than those reported by Gill et al. (1994). The species is expected to be extant in Tonga (R. Fisher pers. comm. 2013), but its status in Tuvalu is uncertain and reports of the recent disruption of natural systems by invasive ants in Tokelau (Lester and Tavite 2004, McNatty et al. 2009) suggest the species is likely to be extinct on Nukunono (R. Fisher pers. comm. 2013). This species is also known to occur in Wallis and Futuna (Adler et al. 1995), but again no recent records exist and the species' status here is unclear (R. Fisher pers. comm. 2013). It is also known from Pukapuka Island of the Danger group (Cook Islands), but extensive surveys by G. McCormack (over six weeks in 2004) have not been able to confirm that the species is still extant here (R. Fisher pers. comm. 2013). It is a coastal species found at low elevations.
The area in which this species is distributed is approximately 3,071 kmÂ². This has been calculated by taking the sum of the areas of each of the islands it inhabits.
