Neighbour-joining analysis (combined COI and cytB data with 1000 bootstrap replicates in PAUP*). The analysis included all 537 sampled individuals, shown here are the 479 individuals within Pariaconus. Described species and recognized forms are indicated as well genotypic clusters within forms. Regional locations for sampling sites within islands are shown to give an idea of geographic clustering and isolation (e.g. P. pele form pele cluster 1 has regionally distinct clusters, whereas P. pele form pele cluster 2 is composed of regionally mixed clusters). Support (80-100%) is indicated for major nodes only.
