Parsimonious haplotype network of mitochondrial DNA sequences of Pseudorhodeus tanago (Hap01–10). Each line connecting haplotypes indicates one nucleotide difference. Small open circles stand for missing haplotypes. Locality number (#) and number of individuals observed (parentheses) indicate haplotype sharing. Blue solid lines encircle haplotype groups (north, center, west and south). Blue broken line indicates sub-grouping within the south haplotype group exhibited by SAMOVA analysis (right, south_1; left, south_2).
