title: Data from: Genetic structure of an introduced paper wasp, Polistes chinensis antennalis (Hymenoptera, Vespidae) in New Zealand

description: Several eusocial wasps are prominent invaders to remote islands. The paper
 wasp Polistes chinensis antennalis is native to East Asia, was introduced
 to New Zealand in 1979, and has expanded its distribution there. This
 provides an excellent opportunity to examine the impacts of an initial
 bottleneck and subsequent expansion on genetic structure. We analysed and
 compared the genetic population structures of the native (Japan and South
 Korea) and invasive New Zealand populations. Although 94% of individuals
 had shared haplotypes detected across both populations, the remaining 6%
 had private haplotypes identified in only one of the three countries. The
 genetic variation at microsatellite loci was lower in New Zealand than in
 native countries, and the genetic structure in New Zealand was clearly
 distinct from that in its native range. Higher frequencies of diploid male
 and triploid female producing colonies were detected in New Zealand than
 in the native countries, showing the reduction of genetic variation via a
 genetic bottleneck. At least two independent introductions were suggested,
 and the putative source regions for New Zealand were assigned as Kanto
 (central island) and Kyushu (south island) in Japan. Serial founder events
 following the initial introduction were also indicated. The estimated
 dispersal distance between mother and daughter in New Zealand was twice
 that in Japan. Thus, the introduction history of P. chinensis antennalis
 in New Zealand is likely the result of at least two independent
 introductions, passing through a bottleneck during introduction, followed
 by population expansion from the point of introduction.
