Bayesian phylogenetic analysis of haplotype sequences hp01-hp31 of S. polychroa. hlE03 (S. lugubris, biotype E) and hlF01 (S. nova, biotype F) were used as outgroups. Numbers adjacent to the nodes indicate the posterior probability for the Bayesian analysis. Locality names are followed from left to right by ploidy number (between brackets), locality name (between square brackets) and haplotype code. Haplotypes with equal number but followed by a different letter (e.g. hp03a, hp03b, hp03c, etc.), represent identical haplotypes (identical COI sequences) found in animals with different ploidy and/or from a different geographical locality. Grey boxes highlight all sexual (diploid) S. polychroa included in this study. Outgroup branch with dashed line has been shortened for aesthetics of the figure.
