After analysis, the outgroup branch was removed for clarity. Numbers to the left of the nodes indicate the quartet puzzling support for each internal branch. The scale bar indicates an evolutionary distance of 0.01 nucleotides per position in the sequence. Vertical distances are for clarity only. Unreliably aligned regions were removed, and the final length of the alignment was 1692 columns.
Aligned sequences are available from the authors upon request.
Samples were also amplified by using sets of PCR primers designed on the basis of the primers described above, but with the restriction sites removed.
