*No. base substitutions/site or amino acid (aa) differences from averaging over all sequence pairs within or between each lineage are shown. Analyses were conducted by using the Kimura 2-parameter model and the pairwise distance at the nucleotide (nt) and aa levels, respectively. All positions containing gaps and missing data were eliminated. SES were obtained by a bootstrap procedure (1,000 replicates).
