Bayesian phylogenetic tree representing the relationships between extant species in the family Partulidae from the Mariana Archipelago. This figure is an adaptation from one published in Sischo and Hadfield (2017). The phylogeny contains sequences from 24 individuals with unique haplotypes from seven islands and is based on a concatenated alignment of three genes (CO1, 16S and ITS2). The combined sequence length was 1683 base pairs. Maximum likelihood and Bayesian analyses recovered comparable topologies. Therefore, Bayesian posterior probabilities and maximum likelihood bootstrap values are reported on all nodes greater than 0.80 or 80% respectively. Branch ends have been collapsed to emphasize support for the species groups, rather than within group relationships. Also, note that this phylogeny does not include the newly sequenced haplotypes of Partula lutaensis sp. nov. mentioned above.
