Maximum likelihood tree showing an overview of the inferred phylogenetic relationships of Windward Island partulid mt COI genotypes. The partulid genus Eua, restricted to central Pacific islands in Samoa, American Samoa and Tonga, served as the outgroup [42] and the grey background applied to the Partula clade visually distinguishes the two ingroup genera. Partula tip clades were taxonomically polyphyletic and the six Moorean tip clades are numbered in bold, as were the five Tahitian clades previously characterized [36]. Terminal Moorean haplotypes are color-coded according to their sample source: Burch 1970 Museum specimens; captive snails; extant wild populations. Two divergent Moorean mt haplotypes were recovered from single snails and are labeled individually: a captive P. suturalis vexillium and an extant wild Mt. Tohiea P. taeniata simulans (identified by J. Murray). A photograph of the latter specimen, taken in the field by J.Y. Meyer, is inserted. Support levels are given above major internal branches; Bayesian posterior probabilities (> 70) on the left and maximum parsimony bootstrap support values (> 50) on the right.
