Minimum-spanning network of haplotypes from this study combined with those from Fernando et al (2000). The numbers against crosshatches indicate polymorphic positions between haplotypes. Positions with both transitional and transversional changes are denoted by ‘a’ and ‘b’, respectively. The dotted lines show alternate connections. Distances between haplotypes are proportionate to the pairwise differences between them, with the exception of BF–BQ and BJ–BQ. Locations sampled in Fernando et al's (2000) study in the mainland included Bhutan (n=13), northeastern India (n=6), Laos (n=14), and Vietnam (n=4), and samples from Sri Lanka included 18 samples from northern Sri Lanka (haplotypes BH, BI, BJ, BK, BL), 25 from mid-latitude Sri Lanka (haplotypes BH, BL, BM, BN, BO, BP), and 38 samples from southern Sri Lanka (haplotypes AE, AF, AG, BL, BP). BQ was the only β clade haplotype on the mainland, found at a frequency of 0.071 in Laos.
